Abstract

PURPOSE: To obtain a highly water-swelling polymer by alkali-treating a specific acrylic copolymer.
CONSTITUTION: A copolymer, obtained by copolymerization of at least 30mol% one or more monomers (A) of the formula[where X is H or CH3, Y is CN, CONH2, COOH, COOM (M is an alkali metal), or COOR (R is an alkyl group)]and 0.5W 2.5mol% one or more of vinyl (vinylidene) bromide and vinyl (vinylidene) iodide (B), is treated with an aqueous alkali solution, e.g., of potassium hydroxide, sodium hydroxide, etc. The copolymer so treated can absorb water in an amount of approx. 2,000 times as much as its own weight without showing any fluidity.
