Patent number: 4377525Abstract: Novel, unsaturated diacetylene-terminated polyimides and processes for their preparation are disclosed herein. These new polyimides are derivatives of anhydride-terminated aromatic polyimides from which they can be prepared by amidation to provide new unsaturated amide groups having a terminal group containing the structure --C.tbd.C--C.tbd.C--, hereinafter sometimes referred to as "conjugated diynes". These new compositions are more tractable than the original anhydride-terminated polyimides and can be converted at appropriate lower temperatures to crosslinked, insoluble, infusible polymers without by-product formation, thereby extending greatly the applications for which the aromatic polyimides can be employed. Moreover, these new polyimides can undergo the Diels-Alder type of addition with a large number of dienophiles. Certain monomeric materials are also described.Type: GrantFiled: March 2, 1982Date of Patent: March 22, 1983Assignee: Plastics Engineering CompanyInventors: Gaetano F. D'Alelio, deceased, Phillip A.
