Handbook for the Chemical Analysis of Plastic and Polymer Additives, Second Edition by Michael Bolgar,Jack Hubball,Joseph Groeger,Susan Meronek Pdf
Polymers have undoubtedly changed the world through many products that improve our lives. However, additives used to modify the overall characteristics of these materials may not be fully disclosed or understood. These additives may present possible environmental and health hazards. It is important to monitor consumer products for these compounds using high-quality reference materials and dependable analytical techniques. The Handbook for the Chemical Analysis of Plastic and Polymer Additives, Second Edition provides the necessary tools for chemists to obtain a more complete listing of additives present in a particular polymeric matrix. It is designed to serve as a valuable source for those monitoring a polymer/plastic material for regulatory or internal compliance. It also helps analysts to correctly identify the complex nature of the materials that have been added to the polymer/plastic. With 50 additional compounds, this second edition nearly doubles the number of additives in several categories, including processing aids, antistatic compounds, mould release products, and blowing agents. It includes a listing that can be cross-referenced by trade name, chemical name, CAS number, and even key mass unit ions from the GC/MS run. Addressing additives from an analytical viewpoint, this comprehensive handbook helps readers identify the additives in plastics. This information can be used to assess compliance with regulations issued by the FDA, US EPA, EU, and other agencies.
This industrially relevant resource covers all established and emerging analytical methods for the deformulation of polymeric materials, with emphasis on the non-polymeric components.

Chemical Analysis of Additives in Plastics by T. R. Crompton Pdf
International Series in Analytical Chemistry, Volume 46: Chemical Analysis of Additives in Plastics, Second Edition brings together numerous investigations on the characterization, identification, and determination of various types of additives in plastics. This book is divided into five chapters. Chapters 1 and 2 describe first the methods for examining additives present in polymers based on either direct spectroscopy of a cast polymer film or on solvent extraction of total additives from the polymer followed by quantitative chemical or physical analysis for various components in the extract. Chapter 3 discusses the application of thin-layer and column chromatography to the separation and determination of known additives. Chapters 4 and 5 examine the application of combined chromatographic and spectroscopic techniques for the separation and determination of unknown plastics additives. This book will prove useful to plastics manufacturers, researchers, institutions, and universities.

Analysis of Rubber and Rubber-like Polymers by M.J. Loadman Pdf
The first edition of this book (1958) described an analytical situation which had existed for a number of years for maintaining quality control on vulcanizates of natural rubber although the situation had recently been disturbed by the introduction of a range of synthetic rubbers which required identification and quantitative estimation. For the former purpose 'wet' chemistry, based on various imperfectly understood organic reactions, was pressed into service. Alongside this was the first introduction of instrumental analysis, using the infrared spectra of either the polymers or, more usually, their pyrolytic products to 'fingerprint' the material. The identification of a range of organic accelerators, antioxidants and their derivatives which had been intro duced during the 1920s and 30s was, in the first edition, dealt with by a combination of column chromatography and infrared spectroscopy or by paper chromatography. Quantitative procedures were, however, still classical in the tradition of gravimetric or volumetric assays with an initially weighed sample yielding, after chemical manipulation, a carefully precipitated, dried and weighed end product, or a solution of known composition whose weight or titre, as a percentage of the initial sample, quantified the function being determined. The second edition of this work (1968) consolidated the newer techni ques which had been introduced in the first without adding to them although, in other applications of analytical chemistry, instrumental analysis had already brought about a transformation in laboratory practice.
