Abstract

PURPOSE: To prepare a water-insoluble resin having high water absorption and biodegradability, by polymerizing starch or cellulose, a specific monomer and a small amount of a crosslinking agent, and thereafter hydrolyzing the polymer.
CONSTITUTION: (A) Starch and/or cellulose, (B) a monomer having an polymerizable double bond and soluble in water when hydrolyzed (e.g. methyl acrylate, acrylonitrile, N-hexylacryl-amide, etc.), and (C) a crosslinking agent (e.g. di- or triacrylic ester) are polymerized by radiation, electron radiation or a ceric salt and hydrogen peroxide, and hydrolyzed. The preferable weight ratio (A):(B):(C) are 100:10W1000:0.0001W10, respectively.
EFFECT: The resin is storable for long period, comparably inexpensive and easily disposed, and therefore useful as paper diapers, sanitary napkins, etc.
