ABSTRACT:
Novel compositions comprising polymerization products of polyimide derivatives having terminal acetylenic amide groups and processes for their preparation are disclosed herein. These new compositions are primarily polymers of derivatives of anhydride-terminated aromatic polyimides from which these derivatives are prepared by amidation to provide acetylenic amide groups having terminal --C.tbd.CH groups as hemi-amic acid groups or their derivatives. These derivative compositions are more tractable than the original anhydride-terminated polyimides and can be converted at appropriate lower temperatures and in accordance with the practice of this invention to crosslinked, insoluble, infusible polymers without by-product formation thereby extending greatly the applications for which the aromatic polyimides can be employed. Also included are polymers from monomeric compounds containing acetylenic amide groups derived from monomeric tetracarboxylic dianhydrides.
