METHOD FOR PRODUCING POLYASPARTIC ACID CROSSLINKED PRODUCT AND CROSSLINKED PRODUCT OBTAINED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a new crosslinked product of a polyaspartic acid which has biodegradability, is usable as a thickener and a water-absorbing resin and changes water absorption by controlling crosslinking density. SOLUTION: The method for producing the crosslinked product of the polyaspartic acid comprises crosslinking an allyl group-containing polysuccinimide with a radical initiator and hydrolyzing the crosslinked product.
