ABSTRACT:
A carbinol-containing polyimide oligomer terminated with epoxide-reactive end groups has the structure ##STR1## wherein Ar is ##STR2## R.sup.1 and R.sup.2 are independently divalent organic radicals; R.sup.3 is a trivalent organic radical; Y is an epoxide-reactive group (e.g.); m is 0 or 1 and n is 0-10. Suitable epoxide-reactive groups include a phenol, thiol, amine, or carboxyl group. Polyimide-polyepoxide adducts are prepared by reacting the polyimides with a polyepoxide, preferably a diepoxide used in excess. The polyimide oligomers are useful as coatings or adhesives. The adducts are useful as adhesives, for composites, and particularly for impregnating the fiberglass sheets which are used to form circuit boards.
