Abstract

Novel, unsaturated polyimide-polyester polymerization products and processes for their preparation are disclosed herein. The polyimide-esters from which the polymerization products are derived are derivatives of anhydride-terminated aromatic polyimides, from which they are prepared by esterification to provide unsaturated ester groups having a terminal --CH.dbd.CH.sub.2 group. These new compositions are crosslinked, insoluble, infusible polymers produced without by-product formation.
