HIGH POLYMER RESEARCH
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.
