A process is provided for preparing polysuccinimides by forming a polymerization mixture comprising poly(alkylene glycol), maleamic acid and, optionally, one or more other amic acid, heating the mixture to an elevated temperature, and maintaining the mixture at the elevated temperature to form polysuccinimides. Poly(amino acids) can be prepared by hydrolysing the polysuccinimides.

Polysuccinimide polymers comprising 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. Also provided is a process for preparing polysuccinimide polymers by forming a polymerization mixture of poly(alkylene glycol), ammonia, one or more monoethylenically unsaturated poly(carboxylic acid) and, optionally, one or more other monoethylenically unsaturated compound; heating the mixture to an elevated temperature; and maintaining the mixture at the elevated temperature to form polysuccinimide polymers.
