Abstract
A process for the production of a vinyl polymer containing a tertiary amino group, which comprises subjecting (a-1) a vinyl polymer containing a carboxylic anhydride group obtained by copolymerizing maleic anhydride, itaconic anhydride or mixtures thereof with at least one copolymerizable monomer and (a-2) a compound containing both one primary amino group and one tertiary amino group for each molecule to a ring-opening reaction, and dehydrocyclizing the adduct to form an imide ring containing polymer. A curable resin composition comprising the resulting polymer and a polyepoxy compound as essential ingredients.
