Patent

Description

Aromatic epoxy-terminated aromatic polyimides and processes for their preparation are provided. The epoxidized polyimides are prepared by epoxidizing an olefinically unsaturated aromatic imide of the formula: ##STR1## WHEREIN Ar is a divalent aromatic organic radical, Ar’ is a tetravalent aromatic organic radical, the four carbonyl groups being attached directly to separate carbon atoms and each pair of carbonyl groups being attached to adjacent carbon atoms in the Ar’ radical, R’ is a divalent aromatic hydrocarbon radical, and n is a positive integer of at least 1. Preferably, the starting aromatic imide is a styrene-terminated aromatic imide wherein n is at least 4 which is epoxidized with a per-acid.
