HOMOPOLYMERIZATION OF ACETYLENE SUBSTITUTED POLYIMIDE POLYMERS

摘要

Polyimides are prepared from acetylene substituted polyimide oligomers via an addition polymerization reaction which involves homopolymerization. These polymers exhibit low void content when cured and possess superior thermal stability characteristics and physical properties such as structural strength. One of their unique properties is their ability to be processed into useful articles at moderate pressures and temperatures.
