Polyurethane Polymers Blends And Interpenetrating Polymer Networks

Polyurethane Polymers: Blends and Interpenetrating Networks deals with almost all aspects of blends and IPNs formed by polyurethane, including the thermal, mechanical, morphological, and viscoelastic properties of each blend presented in the book. In addition, major applications related to these blends and IPNs are mentioned.

Polyurethane Polymers: Composites and Nanocomposites concentrates on the composites and nanocomposites of polyurethane based materials. Polyurethane composites are a very important class of materials widely used in the biomedical and industrial field that offer numerous potential applications in many areas. This book discusses current research and identifies future research needs in the area.

To the surprise of practically no one, research and engineering on multi polymer materials has steadily increased through the 1960s and 1970s. More and more people are remarking that we are running out of new monomers to polymerize, and that the improved polymers of the future will depend heavily on synergistic combinations of existing materials. In the era of the mid-1960s, three distinct multipolymer combinations were recognized: polymer blends, grafts, and blocks. Although inter penetrating polymer networks, lPNs, were prepared very early in polymer history, and already named by Millar in 1960, they played a relatively low-key role in polymer research developments until the late 1960s and 1970s. I would prefer to consider the IPNs as a subdivision of the graft copolymers. Yet the unique topology of the IPNs imparts properties not easily obtainable without the presence of crosslinking. One of the objectives of this book is to point out the wealth of work done on IPNs or closely related materials. Since many papers and patents actually concerned with IPNs are not so designated, this literature is significantly larger than first imagined. It may also be that many authors will meet each other for the first time on these pages and realize that they are working on a common topology. The number of applications suggested in the patent literature is large and growing. Included are impact-resistant plastics, ion exchange resins, noise-damping materials, a type of thermoplastic elastomer, and many more.

Provides a comprehensive review of interpenetrating polymer networks. Opens with four review chapters by important workers in the field--Sperling, Klempner, Utracki, and Lipatov- and continues with an international penetration of current research. Covers synthesis and structure, miscibility and morphology, structure-property relationships, transport and permeability, and functionalized triglyceride oils.

The term "alloy" as pertaining to polymers has become an increasingly popular description of composites of polymers, parti cularly since the publication of the first volume in this series in 1977. Polymer alloy refers to that class of macromolecular materials which, in general, consists of combinations of chemically different polymers. The polymers involved in these combinations may be hetero geneous (multiphase) or homogeneous (single phase). They may be linked together with covalent bonds between the component polymers (block copolymers, graft copolymers), linked topologically with no covalent bonds (interpenetrating polymer networks), or not linked at all except physically (polyblends). In addition, they may be linear (thermoplastic), crosslinked (thermosetting), crystalline, or amorphous, although the latter is more common. To the immense satisfaction - but not surprise - of the editors, there has been no decrease in the research and development of polymer alloys since the publication of the first volume, as evidenced by numerous publications, conferences and symposia. Continued advances in polymer technology caused by the design of new types of polymer alloys have also been noted. This technolog ical interest stems from the fact that these materials very often exhibit a synergism in properties achievable only by the formation of polymer alloys. The classic examples, of course, are the high impact plastics, which are either polyblends, block, or graft co polymers composed of a rubbery and a glassy polymer. Interpene trating polymer networks (IPN's) of such polymers also exhibit the same, or even greater, synergism.

This is the third volume of Advances in IPNs. Research and development on interpenetrating polymer networks (IPNs) continues to increase at an accelerated pace. the number of publications, patents and symposia worldwide testify to this growth of this important field of polymers. Including a collection of industrial applications of IONs, ranging from new types of adhesives, coatings, elastomers and plastics to composites, RIM and medical applications.

This book examines the current state of the art, new challenges, opportunities, and applications of IPNs. With contributions from experts across the globe, this survey is an outstanding resource reference for anyone involved in the field of polymer materials design for advanced technologies. • Comprehensively summarizes many of the recent technical research accomplishments in the area of micro and nanostructured Interpenetrating Polymer Networks • Discusses various aspects of synthesis, characterization, structure, morphology, modelling, properties, and applications of IPNs • Describes how nano-structured IPNs correlate their multiscale structure to their properties and morphologies • Serves as a one-stop reference resource for important research accomplishments in the area of IPNs and nano-structured polymer systems • Includes chapters from leading researchers in the IPN field from industry, academy, government and private research institutions

This is the first volume of a two-volume work which summarizes in an edited format and in a fairly comprehensive manner many of the recent technical research accomplishments in the area of Elastomers. “Advances in Elastomers” discusses the various attempts reported on solving these problems from the point of view of the chemistry and the structure of elastomers, highlighting the drawbacks and advantages of each method. It summarize the importance of elastomers and their multiphase systems in human life and industry, and covers all the topics related to recent advances in elastomers, their blends, IPNs, composites and nanocomposites. This first volume focuses on advances on the blends and interpenetrating networks (IPNs) of elastomers.
