This article reviews the phase behavior of polymer blends with special emphasis on blends of random copolymers. Thermodynamic issues are considered and then experimental results on miscibility and phase separation are summarized. Section 3 deals with characteristic features of both the liquid-liquid phase separation process and the reverse phenomenon of phase dissolution in blends. This also involves...
An overview of various modeling methods used to understand small angle neutron scattering (SANS) data from homogeneous polymer systems is presented. First, calculations of single macromolecule structure factors are reviewed for many chain architectures and monomer block configurations such as linear, ring, star branched, comb grafted chains and regular “starburst” dendrimers either in the homopolymer...
The electroactive polymers most commonly studied during the past decade include polyacetylene, polyaniline, polypyrrole, polythiophene, polyphenylene, poly(phenylene sulfide), poly(phenylene vinylene) and some non-conjugated polymers, such as the polyvinylpyridine and poly(N-vinylcarbazole). These polymers along with their analogs and derivatives have been selected to illustrate the type and level...
