Abstract : High molecular weight aromatic enyne polyimide thermoplastics are prepared by reacting an aromatic dianhydride with (E)-3,3'-(1-buten-3-ynylene) dianiline alone or in admixture with an aromatic diamine. Because of the presence of the enyne moiety in the polymer backbone, the polymers can be lightly crosslinked to provide solvent-resistant thermoplastics. The polymers are particularly useful in fabricating graphite-reinforced, thermoplastic composites for structural applications. (Author)
