CONTENTS - Polymers and Plastics - Tradename Products and Generic Equivalents - Generic Chemical Synonyms and Cross References -Tradename Product Manufacturers - PREFACE - This compendium serves a unique function for those involved in the chemical industry-it provides the necessary information for making the decision as to which trademark chemical product is most suitable for a particular application. The chemicals included in this second book of the series have their major function as dispersants, solvents, and solubilizers, however, complete cross-referencing is provided for the multiple functions of all the chemicals. The first section which is the major portion of each volume contains the most common generic name of the chemicals as the main entry. All these generic entries are in alphabetical order. Synonyms for these chemicals are then listed. The CTFA name appears alongside the appropriate generic name. The structural and/or molecular formula of the chemical is listed whenever possible. The generic chemical is sold under various tradenames and these are listed here in alphabetical order for ease of reference along with their manufacturer in parentheses. The Category subheading lists all the possible functions that the chemical can serve. Because of differences in form, activity, etc., individual tradenames of the generic chemical are used in particular applications more frequently. These are delineated in the Applications section. The differences in properties. toxicity/handling. storage/handling, and standard packaging are specified in the subsequent sections wherever distinguishing characteristics are known. The second section of the volume TRADENAME PRODUCTS AND GENERIC EQUN ALENTS helps the user who only knows a chemical by one tradename to locate its main entry in section 1. The user can look up this tradename in this section of the book and be referred to the appropriate, main-entry, generic chemical name. The third section GENERIC CHEMICAL SYNONYMS AND CROSS REFERENCES provides a way of locating the main entries by knowing only one of the synonyms. If the generic chemical is not in the volume, it will refer you to the volume in which it is contained. The fourth section TRADENAME PRODUCT MANUFACTURERS lists the full addresses of the companies that manufacture or distribute the tradename products found in the first section.

Polymers for Energy Storage and Delivery

Polymers for Energy Storage and Delivery

Oxford University Press Inc
2013
sidottu
Polymeric materials have been and continue to be a focus of research in the development of materials for energy conversion, storage and delivery applications (fuel cells, batteries, photovoltaics, capacitors, etc.). Significant growth in this field started in the early 1990s and has continued to grow quite substantially since that time. Polymeric materials now have a prominent place in energy research. For polymers, particularly polyelectrolytes, being used in fuel cell and battery applications, the importance of chain microstructure, chain dynamics, and nanoscale morphology on the overall performance characteristics of these materials cannot be overstated. As further advancements are made in polymer chemistry, control of nanostructure and characterization, there is a necessity for organized forums that foster cross-fertilization of knowledge and ideas between experts in polymer chemistry, chemical engineering, and polymer physics. This volume is the result of such a forum. Most of the chapters in this book are based on a cross-section of the oral presentations in a symposium on Polymers for Energy Storage and Delivery held in March of 2011 as part of the 241st ACS National Meeting & Exposition (Anaheim, CA). The book contains 17 chapters presented in two parts. Part one focuses on polymers for battery applications and will cover theory and modeling, novel materials, and materials characterization. Professor Janna Maranas has provided an excellent review of the current state of understanding in polyelectrolytes as ion conductors in batteries. Part two will focus on polymers for fuel cells and will cover novel materials, transport, and materials characterization with a brief introduction into the history of polyelectrolytes for fuel cells and the classes of materials being pursued. Realizing the common role that nanostructure plays in both battery and fuel cell applications, Professor Moon Jeong Park and coworkers have also contributed a chapter demonstrating the role of nanostructured polyelectrolyte systems in energy storage and delivery. In addition, the editors are pleased to have a chapter-contributed by Professor Howard Wang and staff scientists of the NIST Center for Neutron Research-on the most state-of-art, in-situ neutron methods for studying lithium ion batteries.

Polymers from Plant Oils

Polymers from Plant Oils

Alessandro Gandini; Talita M. Lacerda

John Wiley Sons Inc
2018
sidottu
Unique state-of-the-art book on an important topic in renewable materials The purpose of this monograph is to provide a thorough outlook on the topic related to the synthesis and characterization of original macromolecular materials derived from plant oils, an important part of the broader steadily growing discipline of polymers from renewable resources. The interest in vegetable oils as sources of biodiesel and materials has witnessed a remarkable growth of scientific and industrial interest since the beginning of the third millennium responding to the pressing drive to implement sustainability in the energy and materials sectors. The book highlights the most relevant strategies being pursued to elaborate polymers derived from a variety of common oils, by direct activation or through chemical modifications yielding novel monomers. Because glycerol is the main byproduct of biodiesel production, it is treated here as the other logical source of macromolecular synthesis. Each of the different approaches is illustrated by an introductory layout of the underlying chemical mechanisms, followed by examples of notable achievements in terms of the properties and potential applications of the ensuing materials, which span a wide range of structures and performances. In particular, original pathways involving click-chemistry reactions as thiol-ene and Diels-Alder couplings and metathesis polymerizations are discussed and shown to reflect the involvement of a growing number of research programs worldwide.
