    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a water-soluble copolymer of at least one kind of water-soluble N-vinyl lactam and at least one kind of hydrophobic comonomer by the radical polymerization of the monomers in an organic solvent. SOLUTION: A vinyl lactam copolymer is produced by the radical polymerization of at least one kind of water-soluble N-vinyl lactam and at least one kind of hydrophobic comonomer in an organic solvent in the presence of an initiator under refluxing condition. In the above method, a part of the solvent is distilled off after converting 90-99 wt.% of the used vinyl lactam and the polymerization is continued. COPYRIGHT: (C)2007,JPO&INPIT
