Abstract

Process for the preparation of crosslinked copolymers of maleic anhydride, characterized in that it comprises copolymerizing a lower alkyl vinyl ether and maleic anhydride, in the presence of 5 to 25 parts by weight of octadiene 1: 7 per 100 parts by weight of maleic anhydride present in the reaction mixture.
