Abstract

PURPOSE: To prepare a hydrophilic polymer having desired water swellability and swelling power according to the use, by introducing epoxy groups to the unsaturated segment of a specific polymer, and converting the epoxy group to hydrophilic.
CONSTITUTION: A hydrophilic polymer is prepared by (1) introducing 5W100 mol% of epoxy group into a polymer by reacting an organic peracid or peroxide with unsaturated groups of the polymer mainly composed of a block copolymer and/or a graft copolymer having one or more structure of (hard segment)-(unsaturated segment)-(hard segment) in a molecule and composed of 5W95 wt% of the hard segment and 95W5 wt% of the unsaturated segment, wherein the hard segment is a hydrophobic segment having an average molecular weight of ≥1000 and the unsaturated segment is an ethylenic segment having an average molecular weight of ≥1000, and then (2) converting the epoxy group to hydrohilic.
