Polyimide-forming compositions, methods of manufacture, and articles prepared therefrom

Abstract

A polyimide-forming composition includes a polyimide prepolymer, an amine, and a solvent comprising a C1-6 alcohol. A method of manufacturing the polyimide-forming composition is disclosed. The method includes heating a substituted or unsubstituted C4-40 bisanhydride in a C1-6 alcohol to dissolve the bisanhydride, adding a substituted or unsubstituted divalent C1-20 diamine to form a polyimide prepolymer, and adding the amine in an amount effective to solubilize the polyimide prepolymer in the C1-6 alcohol, in a solution of the C1-6 alcohol and deionized water, or in deionized water. A method of manufacturing an article including a polyimide is also disclosed.
