ABSTRACT:
Thermal polymerization of a salt of aspartic acid affords polyaspartate directly without hydrolyzing polysuccinimide. Copolymerization of a salt of aspartic acid with aspartic acid itself affords a copolymer of succinimide and aspartate which may be readily derivatized to produce a sulfonated, phosphonated or hydrophobized polymer.
