Abstract

PURPOSE: The titled resin composition which shows excellent water absorption and swelling in contact with water and has a low water solubility and good strength after swelling, prepared by graft-polymerizing an acryl polymer with a specified ethylenically unsaturated monomer.
CONSTITUTION: 100pts.wt. acryl polymer (e.g., a polymer of water absorption ≤ about 20wt%, comprising a (co)polymer of (meth)acrylic acid (ester) is graft- polymerized with about 20W200pts.wt. ethylenically unsaturated monomer (e.g., acrylic acid or monoalkyl itaconate).
