Abstract
Difunctional aromatic enyne compounds are prepared by the catalytic coupling of substituted monoethynyl compounds. The compounds are useful as monomers in polycondensation reactions for the preparation of high molecular weight, thermally stable thermoplastic polymers. On thermal treatment of the polymers, the enyne groups along the polymer backbones react by interchain reactions to provide the solvent and craze resistance required for application as structural materials.
