Abstract: PROBLEM TO BE SOLVED: To obtain a graft polymer having a high efficiency of linking of a trunk polymer to a branch polymer and being capable of the selection of structures having various functional groups as the structure of the trunk polymer and the structure of the branch polymer by radically polymerizing a vinyl monomer in the presence of a water-soluble polymer essentially consisting of repeating units of an optionally substituted styrene structure. SOLUTION: The trunk polymer used is a water-soluble polymer formed by polymerizing an optionally substituted styrene or a water-soluble polymer formed by copolymerizing styrene or the like with other vinyl monomers (e.g. alkyl maleate). From the viewpoint of obtaining a highly pure graft polymer, it is desirable that the trunk polymer has a weight-average molecular weight of 1,000-3,000,000. The ratio of the branch polymer to the trunk polymer is desirably 5/95 to 95/5 by weight. The trunk polymer, a vinyl monomer, an initiator (e.g. benzoyl peroxide), etc., are fed into a reactor and polymerized at 40-120 deg.C.
