ABSTRACT:
The present invention is directed to a novel class of polynitrile (polycyano) substituted polyimide oligomers and the polyamic acid or ester precursors thereof. The nitrile groups on the oligomers allow the compounds to be cured through addition reactions which result in little or no outgassing. In addition, these oligomers are curable with heat in the presence of catalysts such as those which induce cyano trimerizations. The fully cured polyimides derived from these oligomers have excellent thermal and mechanical properties at high temperatures.
