Abstract:

Chemistry Polymerization of nonconjugated multivinyl monomers is being studied. Representative monomer types, such as triallylmethane, are being synthesized for this study. Efforts toward the synthesis of improved 1,2-poly- butadiene and its use as a precurser to modified polymers continued. Dielectrics Polyacene quinone radical polymers exhibited changes in conductivity and thermal activation energy upon application of the pressure ranges used by Bridgman for metals. There was a 100-fold change in conduction. Mechanical properties of high polymers - present and future studies are discussed on the following phase transitions in polypropylene and polybutene-1, deformation characteristics of spherulites, failure mechanisms in glassy polymers, and flow behavior of polymer melts.
