  • Polyamide preparation with pentaamine cobalt (III) complex catalyst
    Patent number: 4707538
    Abstract: A polyamide is produced by polymerizing at least one of an alpha, beta-unsaturated carboxylic acid and ammonia, an ammonium salt of an alpha, beta-unsaturated carboxylic acid, an alpha, beta-unsaturated nitrile and water, a beta-amino propionic acid or alkyl derivative thereof and an alpha, beta-unsaturated amide and ammonia in the presence of a catalyst comprising a pentaammine cobalt (III) complex.
    Type: Grant
    Filed: December 15, 1983
    Date of Patent: November 17, 1987
    Assignee: The Standard Oil Company
    Inventors: Mu-Yen M. Wu, Lawrence E. Ball, Gerald P. Coffey
  • Process for the preparation of polyamide from unsaturated nitrile and ammonium salt of unsaturated carboxylic acid
    Patent number: 4590251
    Abstract: Polyamides can be formed in good yields by the copolymerization of at least one alpha, beta-unsaturated nitrile with at least one alpha, beta-unsaturated carboxylic acid or ammonium salt thereof. These polymers are suitable for use as fibers, plastics, films and molding resins.
    Type: Grant
    Filed: December 17, 1984
    Date of Patent: May 20, 1986
    Assignee: The Standard Oil Company
    Inventors: Mu-Yen M. Wu, Lawrence E. Ball
  • 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.
    Type: Grant
    Filed: September 19, 1983
    Date of Patent: June 25, 1985
