SYNTHESIZING METHOD OF POLYSUCCINIMIDE, ITS COPOLYMER, AND DERIVATIVES THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a water-soluble or water-wettable amido/imide polyamic acid as a polysuccinimide, its copolymer, and derivatives thereof.

SOLUTION: A synthesizing method of the polysuccinimide derivatives comprises synthesizing the polysuccinimide by using L-aspartic acid as a starting material in a supercritical fluid (SCF) such as liquid CO2or in supercritical CO2in an organic cosolvent, and about its polymer or its copolymer, further making a ring-opening reaction of a polysuccinamide in water in the presence of an amine.
