Chemical Characterisation of Polyurethanes by M. J. Forrest Pdf

This review aims to introduce the chemistry of polyurethanes, and to examine the different techniques which may be used to analyse these polymers. The characterisation of polyurethane starting materials, cure reaction, polymer structures and molecular c099, and additives, and their relationship to the final properties of the polymer are all outlined. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.

Eco-Friendly Waterborne Polyurethanes by Ram K. Gupta,Ajay Kumar Mishra Pdf

The polyurethane industry is among the fastest growing, with polyurethanes used in consumer as well as industrial sectors. Waterborne polyurethanes (WPUs) exhibit many advantages over conventional volatile organic compounds (VOCs) based polyurethanes and have emerged as an environmentally friendly alternative. WPUs offer an opportunity to use sustainable raw materials to produce environmentally sustainable polymers, particularly, polyols derived from vegetable oils. Eco-Friendly Waterborne Polyurethanes: Synthesis, Properties, and Applications provides state-of-the-art knowledge of the synthesis, application, and property enhancement of WPUs. Covers various types of eco-friendly materials and technologies used to synthesize WPUs Presents an overview and applications of WPUs in several advanced research areas Provides fundamentals of synthetic processes and their chemistries for specific applications Elaborates on advanced approaches used to convert renewable resources into polymers Offers new direction to scientists, researchers, and students to better understand the chemistry, technologies, and applications Written for polymer chemists, materials scientists, and other researchers and industry, this book serves as a comprehensive reference for readers interested in the development and application of sustainable polymers.

Linear Polyurethanes by Piotr Król Pdf

This volume describes in detail the mechanisms of the diisocyanates and polyols polyaddition process as well as its kinetic and process aspects important for obtaining linear polyurethanes. General kinetics of the process and its experimental verification, using GPC chromatography as well as NMR spectroscopy and MALDI-ToF spectrometry, are presented. Accompanied by over 400 references, the author presents synthesis methods, physicochemical properties of linear polyurethanes (analyzed with DCS, TG, DMTA, Rtg, AFM microscopy methods) as semiproducts for foams, elastomers, lacquers and coatings. Research results concerning free surface energy of the polyurethane coatings are also presented. Special attention is given to the latest polyurethane applications, such as ecological waterborne dispersions, biodegradation resistant elastomers and coatings used as medical implants and binders for ceramic powder materials. Moreover, the book contains information on urethane-isocyanate prepolymers applications, which are potential semifinished products for elastomers, foams, coatings, adhesives and interpenetrating polymer network composites.

Aspects of Polyurethanes by Faris Yılmaz Pdf

Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Because a variety of diisocyanates and a wide range of polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applications. During World War II, a widespread use of polyurethanes was first seen, when they were used as a replacement for rubber, which at that time was expensive and hard to obtain. During the war, other applications were developed, largely involving coatings of different kinds, from airplane finishes to resistant clothing. Subsequent decades saw many further developments and today we are surrounded by polyurethane applications in every aspect of our everyday lives. While polyurethane is a product that most people are not overly familiar with, as it is generally "hidden" behind covers or surfaces made of other materials, it would be hard to imagine life without polyurethanes.

Rethinking Polyester Polyurethanes by Anonim Pdf

Rethinking Polyester Polyurethanes: Algae Based Renewable, Sustainable, Biodegradable and Recyclable Materials explains how and why bio-based materials, specifically algae, will change the polymer industry. The book provides background on algae, polyurethanes (PUs), and their everyday use. It covers the biology and chemistry behind how and why these materials are engineered to be both biodegradable and, through the process of depolymerization, fully recyclable. Chapters cover Re-evaluating the Sources, Redefining the Analytics, Reformulating Polyester Polyurethanes, and The Future. The latter part of the book describes the landscape of bio-based materials, the eco-consumer, and insights into the industry problem of “greenwashing. This book is a valuable resource for industry professionals who use polyurethanes in the supply chain for manufactured products, those in sales and marketing or regulatory roles who wish to better understand the unique advantages of bio-based materials, and researchers studying R&D of biobased polyurethanes or remediation of microplastics pollution on land and in bodies of fresh and saltwater worldwide. Builds on the foundation of sustainable, renewable, biodegradable, recyclable microplastics, with lifecycle assessment, techno-economic analysis, and the green premium Clarifies the true economics—if we were to go back to initial development of the plastics industry, what would we do differently? Covers the basic science—the knowledge required to effectively communicate the use of materials that are on first examination more expensive, but on closer examination less expensive when environmental consequences are factored
