Abstract
A method for producing an acrylonitrile crosslinked copolymer, which comprises copolymerizing, as polymerizable monomers, acrylonitrile, an alkyl ester of acrylic acid or methacrylic acid, an aliphatic or alicyclic crosslinkable unsaturated monomer having at least two allyl groups, and an aromatic crosslinkable polyunsaturated monomer, in the presence of from 10 to 45% by weight, based on the total amount of the polymerizable monomers, of an inert organic solvent having a specific gravity of at least 1.0.
