Polymeric Dispersions Principles And Applications

A comprehensive and up to date survey of the science and technology of polymeric dispersions. The book discusses the kinetics and mechanisms of polymerization in dispersed media, examines the processes controlling particle morphology, presents both off-line and on-line methods for the characterization of polymer colloids, considers reactor engineering and control, and covers a wide variety of applications, such as latex paint formulations, encapsulation of inorganic particles, reactive latexes, adhesives, paper coating, and biomedical and pharmaceutical applications. Audience: A valuable resource for scientists and engineers, academic and industrial, who are involved in the manufacture or application of polymeric dispersions.

Aqueous polymer dispersions are environmentally friendly and therefore they have replaced in many applications polymers dissolved in organic solvents. This substitution process is still ongoing. This book discusses the world of aqueous polymer dispersions from the viewpoint of how they are applied. For a better understanding it starts with a general description of the synthesis of polymer dispersions and their characterization. The following chapters are dedicated to a wide variety of applications, including history, modern processes, and typical formulations and performance. The selection and the usage of a polymer dispersion are not uniform around the world because of historical and regional differences of the technical developments and marketing demands. Leading scientists from industry contributed to this book ensuring that practical issues are emphasized.

"This comprehensive guide illustrates the effects of dispersions in applications, the means necessary to achieve these effects with optical results, and how to overcome or avoid the difficulties encounteredemphasizing the dispersions of solid particles in liquid or solid media."

The incessantly interest in aqueous polymer dispersions (APD) since more than 90 years can be related to the almost unlimited possibilities to tailor APD to specific needs. These proceedings from an international symposium on "Polymer Colloids: Preparation & Properties of Aqueous Polymer Dispersions" held at the Swabian Conference Center (Kloster Irsee, Germany) witness this statement. The 33 contributions cover important aspects of APD such as control of particle size and stabilization, different polymerization technologies, applications as binders, paints, or as supports for proteins and hence, span the whole range from academic to practical.

The 8th Smithers Rapra conference on Latex and Synthetic Polymer Dispersions gave a very broad picture of the industry. These proceedings cover all the presentations from the two day event which included: The scientific principles underlying latex dipping were described by Professor C. C. Ho, and Dr, Aik Hwee Eng of Ansell spoke about a modern result of dipping - the antimicrobial glove. Very interesting observations about the allergenic potential of synthetic latex gloves compared to those dipped from natural rubber were made by Hardi Tamm of Korymbos. The use of gamma radiation from the very start of the process, as a means of prevulcanization, to the end of the production process, in sterilization, was described by Dr. Rosamma Alex of the Rubber Research Institute of India and Eric Beers of Nordion respectively. The versatility of natural latex was demonstrated in a paper by Dr. Azura of Universiti Sains Malaysia, who showed us how it can be used for the cleaning of compression moulds. Innovative polymer synthesis in the manufacture of latex dispersions was presented by Dr. Joachim Storsberg of the Fraunhofer Institute, and Dr. Soeren Butz of Synthomer told how more clever chemistry could be used to "e;tailor-make"e; pressure sensitive adhesives. The environmental side of the industry was not forgotten, with two presentations from the Malaysian Rubber Board - Muhammad D Syraarani describing an environmentally friendly method for the analysis of magnesium in latex and Dr. Devaraj Veerasamy presenting the use of ultrafiltration to process latex. In a similar vein, Prof. Khairah Haji Badri, of the Universiti Tun Abdul Rahman showed how natural resources such as palm oil can be used to create useful polymers. David Hill of David Hill and Associates described how to carry out Process Validation of dipped condoms and gloves, and the delegates were told how the newest latex for dipping - synthetic polyiosprene - compares with the oldest - natural rubber - by Dr. Bert Krutzer of Kraton. The conference ended with Dr. Siby Varghese of the Rubber Research Institute of India, and Prof. Sabu Thomas of the Mahatma Gandhi University describing recent advances and applications in the field of nanotechnology.

This reference describes the important phases and applications of polymeric surface active materials - including colloid stabilization and solution properties, syntheses with various techniques, and uses in polymerization as stabilizers and as compatibilizers in incompatible polymer blends.;Written for scientists involved in research fields other than polymer colloids, this book discusses colloid stabilization by polymeric surfactants in aqueous and nonaqueous systems, as well as custom synthesis of these materials. It examines their uses as stabilizers in heterophase polymerizations and considers the phenomenon of adsorption at surfaces and interfaces. The properties and characteristics of such compounds as polyelectrolytes, polyampholytes and hydrogels are clarified.;Containing many drawings and tables, this book is for materials scientists, chemists, engineers and physicists in the polymer industry working with paints, adhesives, elastomers and blends.
