Abstract

PURPOSE: To prepare a hydrophilic polymer having excellent water-swellability, degree of swelling with water, and gel-storage stability, by introducing a hydrophilic group to the ethylenic unsaturated group in a polymer mainly cmposed of a specific block- or graft-copolymer.
CONSTITUTION: A hydrophilic group is introduced into an ethylenic unsaturated group in a copolymer mainly composed of a block- or graft-copolymer having a structure of (hard segment)-(unsaturated segment)-(hard segment) wherein the content of the unsaturated segment is 95W5 wt.% and its average molecular weight is ≥1000, and the content of the hard segment is 5W95 wt.% and its average molecular weight is ≥1000, by reacting the copolymer composition with an α, β- ethylenic unsaturated carboxylic acid (derivative) at 150W300°C in an inert solvent under inert gas pressure.
