摘要：
Method of producing copolymers by free-radical polymerization of at least one water-soluble N-vinyllactam and at least one hydrophobic comonomer in an organic solvent in the presence of an initiator, where the polymerization is carried out under a gauge pressure such that evaporation of the components is avoided.
