ABSTRACT:
Polysuccinimide polymers of from about 5 to 100 percent by weight of methylenesuccinimide moieties, and from 0 to about 95 percent by weight of one or more amino acid moieties are provided. A process is provided for preparing polysuccinimide polymers by forming a polymerization mixture of poly(alkylene glycol), ammonia, one or more monoethylenically unsaturated poly(carboxylic acids) and, optionally, one or more other monoethylenically unsaturated compounds; heating the mixture to an elevated temperature; and maintaining the mixture at the elevated temperature to form polysuccinimide polymers.
