Rotations around torsional barriers induce changes in chain conformation. For conjugated systems like polydiacetylenes, flow-induced changes in chain conformation can have a profound influence on the photon absorption and electronic conductivity properties of the material [73]. Flow-induced changes in molecular conformation form the basis for several technically important processes, the best known examples are the production of oriented fibers by gel spinning [74], the compatibility enhancement [75] and the shear-induced modification of polymer morphology [76].

In the years since controversies concerning the chemical structure of such major polysaccharides as cellulose and starch were resolved, the polysaccharide chemist has had little need for x-ray information in working out details of chemical structure. Indeed, the number of detailed x-ray studies on polysaccharides is so much smaller than the number of chemical studies that it is easy to understand why this subject has not been reviewed in this Series previously. Nevertheless, the great commercial importance of cellulose fibers and cellulose derivatives, and the influence of fiber morphology on reactivity, have resulted in a considerable volume of x-ray work relative to this particular material. A review on polymer unit-... [Pg.421]

In the development of polymeric materials, matrix polymer is the most important raw material used. Polymers are complex materials and require exhaustive consideration because many properties can be achieved by selection of polymer or polymer blending can be used to obtain a special set of properties required for application. Chapter 2 is all devoted to PVC, which is the major polymer used in PVC Formulary. Different grades, which are available commercially are discussed to facilitate selection of polymer for different purposes. Characteristics of polymer grades depend on the method of production, specifically on the type of polymerization, each having strong influence on polymer morphology and composition. But properties are also tailored to the potential applications, variety of which is illustrated by Figure 1.1. [Pg.3]
