Abstract

PURPOSE: To prepare a hydrophilic polymer insoluble in water and having excellent water absorption properties, by introducing sulfonic acid groups, etc. to the unsaturated groups of a graft copolymer having specific chain structure.
CONSTITUTION: a hydrophilic polymer is prepared by introducing sulfonic acid groups, their derivatives or their salts to the unsaturated groups of a polymeric substance consisting mainly of a block copolymer and/or a graft copolymer having a chain structure of B-A-B, wherein A is an ethylenic unsaturated group-containing segment having an average molecular weight of ≥ 1,000 (e.g. polybutadiene, etc.), and B is a hydrophobic hard segment having an average molecular weight of ≥ 1,000 (e.g. poly-α-methylstyrene, etc.), at a conversion preferably of 5-100 mol %.
