Abstract of the Disclosure: Copolymers of ethylenically unsaturated dicarboxylic anhydrides and alkyl vinyl ethers are prepared by copolymerization of the monomers from which the copolymers are derived, in the presence or absence of up to 2%X by weight, based on the monomers, of a crosslinking agent containing two or more ethylenically unsaturated double bonds, in the presence of a polymer- ization initiator in an ester of not less than 5 carbon atoms which is obtained from a saturated aliphatic car- boxylic acid and a saturated monohydric alcohol, as a solvent for the monomers, by a precipitation polymeriza- tion method.
