ABSTRACT:
Polymers possessing imide groups are disclosed. These polymers display good impact strength and are obtained by reacting:
A. a bis-imide of the formula ##EQU1## in which Y represents a divalent hydrocarbon radical with 2 to 20 carbon atoms which is free from unsaturated bonds other than aromatic bonds, a divalent mono- or bis-heterocyclic radical with 2 to 10 carbon atoms, or a divalent organic radical with 4 to 20 carbon atoms consisting of several of the hydrocarbon radicals defined above connected to one another by --O--, --S--, --CO-- or --SO.sub.2 --, and
B. either an adduct (A) obtained by reacting an epoxy resin and a polyamine of the general formula:
