Ultrastructure Processing and Characterization of Polymers
Abstract
During this period the research program contained components dealing inter alia with polymer blends, electro- and optically-active polymers, computer simulation of blend phenomena, dynamic light scattering measuring diffusion in porous media, and aspects of ultrastructural processing. New state-of-the-art instrumentation was developed, including a two-dimensional x-ray system and solid state NMR. In the area of polymer blends we have continued to emphasize the effect of chain microstructure on miscibility in multi-component systems. This has involved phase behavior studies of copolymer-containing blends, where the structure of the copolymer have been varied in terms of chemistry, tacticity and/or sequence distribution. In the electro-active polymer area, we have concentrated on research involving poly(p-phenylene vinylene) (PPV) and its derivatives, copolymers, and blends. The electrical and, more recently, the non-linear optical properties of this family of conjugated polymers has proved to be of particular interest and potential applicability. Keywords: Polymer chemistry; Physical properties; Molecular physics.
