Polymers are substances containing a large number of structural units joined by the same type of linkage. These substances often form into a chain-like structure. Starch, cellulose, and rubber all possess polymeric properties. Today, the polymer industry has grown to be larger than the aluminium, copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Current applications extend from adhesives, coatings, foams, and packaging materials to textile and industrial fibres, elastomers, and structural plastics. Polymers are also used for most composites, electronic devices, biomedical devices, optical devices, and precursors for many newly developed high-tech ceramics. This new book presents leading-edge research in this rapidly-changing and evolving field.

This book represents the proceedings of the First International Conference on Frontiers of Polymer Research held in New Delhi, India during January 20-25, 1991. Polymers have usually been perceived as substances to be used in insulations, coatings, fabrics, and structural materials. Defying this classical view, polymers are emerging as a new class of materials with potential applications in many new technologies. They also offer challenging opportunities for fundamental research. Recognizing a tremendous growth in world wide interest in polymer research and technology, a truly global "1st International Conference on Frontiers of Polymer Research" was organized by P. N. Prasad (SUNY at Buffalo), F. E. Karasz (University of Massachusetts) and J. K. Nigam (Shriram Institute for Industrial Research, India). The 225 participants represented 25 countries and a wide variety of academic, industrial and government groups. The conference was inaugurated by the Prime Minister of India, Mr. Chandra Shekhar and had a high level media coverage. The focus of the conference was on three frontier areas of polymer research: (i) Polymers for photonics, where nonlinear optical properties of polymers show great promise, (ii) Polymers for electronics, where new conduction mechanisms and photophysics have generated considerable enthusiasm and (iii) High performance polymers as new advanced polymers have exhibited exceptionally high mechanical strength coupled with light weight.

It is generally accepted that a new material is often developed by ?nding a new synthesis method of reaction or a new reaction catalyst. Historically, a typical example may be referred to as a Ziegler–Natta catalyst, which has allowed large-scale production of petroleum-based polyole?ns since the middle of the 20th century. New polymer synthesis, therefore, will hopefully lead to creation of new polymer materials in the 21st century. This special issue contributed by three groups focuses on recent advances in polymer synthesis methods, which handle the cutting-edge aspects of the advanced technology. The ?rst article by Yokozawa and coworkers contains an overview of the - action control in various condensation polymerizations (polycondensations). Advanced technologies enabled the control of stereochemistry (regio-, g- metrical-, and enantio-selections), chemoselectivity, chain topology, and st- chiometry of monomers, giving a high molecular weight polymer. It has been recognized for a long time, however, that polycondensation is a dif?cult p- cess in controlling the reaction pathway, because the reaction is of step-growth and the reactivity of monomers, oligomers, and polymers are almost the same during the reaction and hence, the molecular weight of polymers and its d- tribution (M /M ) are impossible to regulate. The authors’ group developed w n a new reaction system (chain-growth condensation polymerization), changing the nature of polycondensation from step-growth to chain-growth; namely the propagating chain-end is active, allowing for control of the product molecular weight as well as the distribution.

Professor Brian Vincent is a leading light in colloid science both in the UK and internationally. The science Brian has been involved in has influenced many areas of colloids both academically and industrially. He has collaborated with many sectors of industry (including pharmaceuticals, petrochemicals, agrochemicals, personal products, laundry products, paints and coatings). Brian has also been an active member of both the RSC and the SCI and has collaborated with many universities in the UK and overseas. Brian Vincent retired from the position of Leverhulme Professor of Physical Chemistry at the University of Bristol at the end of 2007 after a long and distinguished career which started as a chemistry undergraduate in Bristol in 1961. After obtaining a 1st class honours degree in Chemistry and an MSc in Surface Chemistry and Colloids and a PhD, Brian then moved to Wageningen to work in Hans Lyklema's laboratory on a Royal Society Fellowship. This was to be the start of a lifelong friendship and scientific collaboration with the Colloid and Physical Chemistry Group there. After returning to the UK in 1969, Brian had a succession of top posts and appointments culminating in 1993 when he became the 5th Leverhulme Professor in Physical Chemistry. In 1994, together with Dr Jim Goodwin, Brian founded the very successful Bristol Colloid Centre, an organisation which carries out short-term research and consultancy work for industry. Brian has received many honours including the SCI Founder's Lecture and Award, the SCI Distinguished Service Award, the RSC award in Surface and Colloid Chemistry and the Rehbinder Lecture and Medal (Moscow). He has had numerous invitations to give lectures throughout the world and has published over 250 papers, articles, books and patents during his career. He has also been very active at the academic /industry interface and has been a consultant for many of the leading companies that use colloid technology worldwide. This unique book is effectively a compendium of Brian's research, complemented by contributions on current topics in colloids by some of the leading scientists in the field. It provides an overview of the broad spectrum of colloid and interface science in which Brian has been a research pioneer for many years. The contributors to this symposium volume comprise a selection of Brian's past students and postdocs who have themselves pursued academic careers and other colleagues with whom he has worked extensively, all of whom are of international standing in colloid science and as such make this book an invaluable reference tool. The book backs up a meeting organised jointly by the RSC Colloid and Interface Science Group and the SCI Colloid & Surface Science Group and covers topics such as: " The Adsorption of Small, Negative Particles onto Large Positive Particles " Polymer Chemistry, Hypervelocity Physics and the CASSINI Space Mission " The BV Droplets Downunder: From Model Emulsions to Drug Delivery " Polymers and Surfactants at Interfaces " Controlled Release as Desorption from Porous Polymeric Systems " Characterisation and Application of Colloidal Micorogels " Surface Modification The range of the subject material highlights Brian's own very broad interests in colloid science; it also reflects his long-standing interest in both the academic fundamentals as well as practical applications of the subject. The volume is dedicated to Brian in recognition of his considerable contribution to the world of colloid science and to the guidance and inspiration he has given to many future generations of colloid scientists. However, the book is not just reflective, but provides insight into new areas in which colloid science is being applied. It has specific appeal to both colloid scientists in academia and industry who will find this book fascinating as well as an indispensable reference tool.

Ringed compounds are very unique in Nature, because the human skeletal foundation as will be seen in Vol VI), from the Head to the Toes are made of ringed compounds (the steroids). It is from the Chemistry of ringed compounds, one can see the Physics of Springs with respect to many concepts such as Strain Energies. There are rings which cannot be opened and there are others which can readily be opened. How rings are formed and opened are unknown to Chemists universally; but they think they know. The characters of rings, the conditions favoring their openings, expansions and reduction in size and formations, the manners by which rings are opened or closed, etc. have been clearly explained. Having covered virtually every type of rings, all the different types of resonance stabilization and molecular rearrangement phenomena and other phenomena present in these systems have begun to be fully identified. For the first time for example, how meta, ortho- and para-substitutions take place in benzene rings, 2-,5- positions or 3-,4- positions substitutions take place in pyrrole, furan and thiophene rings etc. have been clearly explained based on the types of resonance stabilization phenomena favored by them. After every chapter beginning from Vol (II), Rules of Chemistry were stated relating not only to the materials in that chapter, but also to the past and in fact the future. In the last chapter of Vol (III)B, all rules coming from The beginning of a New Dawn for Humanity and also from Vol (I), were stated. These rules are not just ordinary rules, but an embracement of how Nature operates. Amongst ringed compounds/monomers, there are Males (called Electrophiles) and Females (called Nucleophiles), based on the types of Activation centers carried by them Why some favor being used as monomers and others do not, have been clearly explained. Nucleophilic, electrophilic, radical-pushing and radical-pulling capacities of the compounds and their substituted groups (new) have been provided. Before understanding this Volume, Volumes (I) and (II) as well as The Beginning of a New Dawn for Humanity, must be read. This Volume will find most useful applications to the medical scientists, biochemists, chemical and other related disciplines, where little or nothing is indeed known about ringed compounds.
