ABSTRACT:
Polyaspartic acid having a weight average molecular weight of 1000 to 5000 is produced by hydrolysis of anhydropolyaspartic acid. Anhydropolyaspartic acid is produced by condensation polymerization of L-aspartic acid. Greater than 80% conversion is achievable utilizing "temperature vs time" profiles.
