Abstract
A composition of matter comprising an acetylene-terminated polyimide oligomer and a cure rate inhibitor selected from the group consisting of hydroquinone, maleic acid, glutaric acid, dibetanapthyl para-phenylene diamine. The composition has a retarded cure rate, thereby facilitating the fabrication of void-free molded objects and composites.
