  • Process for the preparation of polyesteramide from cyclic lactone
    Patent number: 4525578
    Abstract: Polyesteramides can be prepared by copolymerizing a cyclic lactone with at least one of an ammonium salt of an alpha, beta unsaturated monocarboxylic acid, an alpha, beta unsaturated nitrile and water and beta-aminopropionic acids and their alkyl derivatives. Polymers with especially good physical properties were prepared by polymerizing caprolactone with one or more ammonium methacrylate, ammonium acrylate, acrylonitrile and beta-alanine. These polymers are useful as molding plastics.
