UN METODO PARA PRODUCIR UN PRODUCTO DE POLIIMIDA

摘要

Novel polyimide products of the general formula where n is from 2 to 20 and each R is hydrogen or a group effective to block further reaction with a diamine. These products are incapable of further polymerization with diamines, but are useful starting materials for reaction with other polyfunctional reagents such as diepoxides to form interesting new resins.
