ABSTRACT:
Aromatic and aromatic heterocyclic enyne polymers are prepared by reacting a di-.beta.-bromovinylbenzene and a diacetylenic compound. The polymers have relatively low glass transition temperatures for fabrication, and after heat treatment exhibit high glass transition temperatures, as well as low solvent susceptibility. Also provided is a new composition of matter 1,4-bis-(cis-.beta.-bromovinyl)benzene.
