Abstract: The present invention relates to a process for preparation of copolymers A) comprising A1) one or more vinylaromatic monomers, A2) one or more vinyl cyanides, and A3) one or more dicarboxylic anhydrides via bulk polymerization or via solution polymerization, an important feature of the invention being that the polymerization is carried out in the presence of from 0.01 to 0.5% by weight of water, based on the total weight of the polymerization mixture. The present invention further relates to the copolymers A), to thermoplastic molding compositions comprising the copolymers A), to the use of the copolymers A) and of the thermoplastic molding compositions, and also to the moldings, foils, fibers, or foams obtainable from the copolymers A) or from the thermoplastic molding compositions.
