Abstract

PURPOSE: To obtain graft-modified starch, excellent in water absorption and surface and useful as physiologycal material, etc., by graft-copolymerizing a monomer such as acrylic acid and another monomer such as hydroxyethyl acrylate, in specified proportions, with starch or various modified starches.
CONSTITUTION: (a) A monomer of formula I (R1 is H or methyl: M is H, alkali metal or ammonium salt), such as (meth)acrylic acid and its alkali metal salts and (b) a monomer of formula II (R2, R3, R4 are H or methyl: R5 is H, 1W5C alkyl, etc.), are graft-copolymerized with at least one kind of starch selected from natural starch such as cornor wheat starch and various modified starches such as carboxymethyl cellulose. Purpose graft-modified starch is obtained by setting the ratio starch: (a) compound:(b) component to 100:5W500:10W200.
