Available in PDF, EPUB and Kindle. Book excerpt: On this, the dawning of a new age in high technology, man is seeking answers to increasingly complex problems. We are routinely launching reusable vehicles into space, designing and building computers with seemingly limitless powers, and developing sophisticated communications systems using laser technology, fiber optics, holography, etc., all of which require new and advanced materials. Polymer alloys continue to provide new solutions to the materials problems, and remain an area of ever increasing research. Polymer alloys are mu1ticomponent macromolecular systems. The components may be all on the same chain (as in block co polymers), on side chains (as in graft copolymers), or in different molecules (as in po1yb1ends and interpenetrating polymer networks). The variety of morphologies possible and the synergistic effects on ultimate properties continue to stimulate research on new polymer alloys. More and more studies on synthesis of new alloys, the kinetics and mecha nisms of their formation, and their characterization, are taking place, as well as studies on their processing and applications. This book presents the proceedings of the Symposium on Polymer Alloys, sponsored by the American Chemical Society's Division of OrganiC Coatings and Plastics Chemistry held at the 182nd meeting of the American Chemical Society in New York, in August, 1981. The most recent efforts of scientists and engineers from allover the world in this increasingly important field are presented in the following pages.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: P. S. HOPE and M. J. FOLKES Mixing two or more polymers together to produce blends or alloys is a well-established strategy for achieving a specified portfolio of physical proper ties, without the need to synthesise specialised polymer systems. The subject is vast and has been the focus of much work, both theoretical and experimental. Much ofthe earlier work in this field was necessarily empirical and many ofthe blends produced were of academic rather than commercial interest. The manner in which two (or more) polymers are compounded together is of vital importance in controlling the properties of blends. Moreover, particular ly through detailed rheological studies, it is becoming apparent that process ing can provide a wide range of blend microstructures. In an extreme, this is exemplified by the in situ formation of fibres resulting from the imposition of predetermined flow fields on blends, when in the solution or melt state. The microstructures produced in this case transform the blend into a true fibre composite; this parallels earlier work on the deformation of metal alloys. This type of processing-structure-property correlation opens up many new possi bilities for innovative applications; for example, the production of stiff fibre composites and blends having anisotropic transport properties, such as novel membranes. This book serves a dual purpose.

Available in PDF, EPUB and Kindle. Book excerpt: Alloy is a term commonly associated with metals and implies a composite which may be sinqle phase (solid solution) or heterophase. Whichever the case, metallic alloys generally exist because they exhibit improved properties over the base metal. There are numer ous types of metallic alloys, including interstitial solid solutions, substitutional solid solutions, and multiphase combinations of these with intermetallic compounds, valency compounds, electron compounds, etc. A similar situation exists with polymers. There are numerous types of composites, or "alloys" of polymers in existence today with new ones being created continuously. Polyblends are simple physical mixtures of the constituent polymers with no covalent bonds occuring between them. As with metals, these may be homogeneous (single phase) solid solytions or heterogeneous (multiple phase) mixtures. With polymers, the latter case is by far the most prevalent situation due to the thermodynamic incompatibility of most polymers. This is due to the relatively small gain in entropy upon mixing the polymers due to contiguity restrictions imposed by their large chain length.

Available in PDF, EPUB and Kindle. Book excerpt: From Reports in Volume 5: "Recently polymer blends have emerged as one of the most important areas of research activity in the field of polymer science and technology. Because of their satisfactory performance in meeting specific needs of the polymer industry, they have drawn considerable attention in replacing not only many conventional materials, but also some of the polymers that are in vogue. By suitably varying the blend compositions and manipulating the processing conditions, tailor-made products with a unique set of end use properties can be achieved at a much lower cost and within a shorter time than would have been necessary for the development of a new polymer. The usefulness of such blends increases with the increasing range of applications of this type of materials." (Chapter 4) "New and growing demands on polymeric materials cannot be satisfied in future by an assortment extension of basic polymers. Although the introduction of new major-use basic polymer is possible, it seems unlikely in view of current projected economic and technical considerations. On the other hand, new products based on the modification of existing polymers have and will continue to be fruitful areas for both scientific and commercial developments. The driving forces for these developments are: 1. Improved performance, 2. Reduced cost, 3. Present, pending and future legislation dealing with health and environmental issues." (Chapter 11)
