Polymers as Aids in Organic Chemistry covers the broad classifications and application of polymers in organic chemistry. This book is organized into 15 chapters that focus on the transformation of polymers and their role in other reagents that must be easily separated from their final product. After a brief introduction to polymer chemistry, the book presents a tabulation of the various types of polymers that have been used and the methods for their characterization. It then discusses the use of polymers as supports in peptide, oligonucleotide, and oligosaccharide chemistry; in peptide sequencing; in monofunctionalized difunctional compounds preparation, as aids in asymmetric syntheses; and as trapping agents in the determination of reaction intermediates. The subsequent chapters describe the use of polymers as catalysts, with particular emphasis on transition metals immobilized in the polymer matrix and used as catalysts. The concluding chapters examine polymer-immobilized compounds, enzymes, and whole cells that have been used to carry out a large number of reaction, most of which impinge on the area of organic chemistry. Polymer scientists and researchers and organic chemists will find this book invaluable.

Derived from the fourth edition of the well-known Plastics Technology Handbook, Industrial Polymers, Specialty Polymers, and Their Applications covers a wide range of general and special types of polymers, along with a wealth of information about their applications. The book first focuses on commonly used industrial polymers, including polypropylenes, low- and high-density polyethylenes, and poly(vinyl chloride), as well as less widely used polymer types, such as acrylics, ether polymers, cellulosics, sulfide polymers, silicones, polysulfones, polyether ether ketones, and polybenzimidazoles. It then explores polymer derivatives and polymeric combinations that play special and often critical roles in diverse fields of human activities. The polymers covered include liquid crystal, electroactive, ionic, and shape memory polymers; hydrogels; and nanocomposites. The volume concludes with a comprehensive overview of new developments in the use of polymers in a variety of areas.

Although the title of this book is Paper Chemistry, it should be considered as a text about the chemistry of the formation of paper from aqueous suspensions of fibre and other additives, rather than as a book about the chemistry of the raw material itself. It is the subject of what papermakers call wet-end chemistry. There are many other excellent texts on the chemistry of cellulose and, apart from one chapter on the accessibility of cellulose, the subject is not addressed here. Neither does the book deal with the chemistry of pulp preparation (from wood, from other plant sources or from recycled fibres), for there are also many excellent texts on this subject. The formation of paper is a continuous filtration process in which cellulosic fibres are formed into a network which is then pressed and dried. The important chemistry involved in this process is firstly the retention of colloidal material during filtration and secondly the modification of fibre and sheet properties so as to widen the scope for the use of paper and board products. As is the fashion these days, each chapter is written by an internationally recognised expert in the field, and my thanks are extended to all of the contributors. for their hours of patient and unseen research during the preparation of their manuscripts.

Ionic polymers are present almost everywhere in the world, biological systems being the most important reservoir of ionic polymers such as nucleic acids, and many proteins, alginic acid and so on. Artificial ionic polymers derived from natural polymers such as chitin, cellulose or starch, by adequate chemical transformations, and a multitude of synthetic ionic polymers are generated in the laboratory. They can contain ionic or ionisable groups. Ionic polymers, either artificial or synthetic, have a multitude of applications such as: stabilisation or destabilisation of dispersions, thickening of solutions, oil recovery aids, water purification, corrosion inhibitors, soil conditioners, anti-static agents, additives in cosmetics and foods, surface modification, and so forth. Solid ionic hybrid materials found applications such as polymer electrolytes or substrates for the organic synthesis in solid phase. Many books and article reviews were dedicated to this wide class of polymers but the permanent diversification of their structures and applications ask for new and updated overviews on this field. Therefore, this book reports updated information from literature as well as original contributions in the field of ionic (co)polymers and hybrids, mainly on the applications of ionic polymers and hybrids such as: self-assembled multi-layers, ionic polymers containing azobenzene chromophore, phase separation processes, chelating ion exchangers, polymer electrolytes, functionalised solid surfaces and ionic hybrid hydrogels.

The Impact Of Chemical Sequencing On Filtration Performance

The primary objective of this research was to understand the impact of chemical sequencing and coagulation pH/zeta potential on filtration performance. The secondary goal was to determine effective coagulation processes in terms of pH, zeta potential, and coagulant dose for treating challenging (i.e., runoff-type) raw waters. The following are highlights from this project: Use of high coagulation pH (approximately 7.5) provided more consistent filtration performance over a wider range of coagulation conditions than lower pH levels. Because higher pH significantly increases the optimum zeta potential range for filtration, a practical implication of this result is that use of a high coagulation pH process may be the most effective short-term treatment strategy for rapidly changing, runoff-type waters containing low alkalinity and high NOM levels. The photometric dispersion analyzer (PDA) appears to be a useful alternative to jar tests for determining optimum coagulant doses and quickly evaluating different coagulation scenarios.

Inorganic chemistry is of great economic and industrial importance. It provides not only metals, fertilizers, construction materials, pigments and glass, but also countless raw materials for the organic chemicals industry. Many modern industrial products (video-cassettes, optical fibers or chips for micro- electronics) would be inconceivable without the application of industrial inorganic chemistry. This book offers a comprehensive description of all these areas: Details on manufacturing processes, important economic aspects, ecological consequences, energy and raw material consumption and many other facts and figures are compiled for easy reference. The book is intended for students, university lecturers, chemists and engineers in industry, businessmen and lawyers. They will find reliable, detailed information that is difficult to obtain from other sources, as well as extensive references and a guide to further reading. The particular value of this book lies in its clear descriptions and its emphasis on the interrelationship between industrial and economic factors.

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.
