PROCESSES FOR PRODUCTION OF POLYASPARTIC ACID PRECURSOR POLYMER AND POLYASPARTIC ACID SALTS

摘要

polymerization using at least one member selected from the reaction product and maleic acid amide of maleic anhydride as a monomer ammonia a method of manufacturing a precursor polymer for poly- aspartic acid , poly- aspartic acid production process of the precursor polymer at least part of the carboxyl groups of the monomer , characterized in that the tertiary amine salts; and , a poly aspartic acid precursor polymer obtained in this manner with an aqueous base solution is industrially inexpensive , characterized in that the treatment is also easy poly aspartic acid salt thereof is disclosed .
