Method of producing vinyllactam 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 under reflux conditions, where at least 10 mol % of the N-vinyllactam are added to the polymerization mixture when at least 90 mol % of the hydrophobic monomer have completely reacted.
