  • Water-soluble polyester imide resin wire coating process
    Patent number: 4206261
    Abstract: Water soluble polyester-imide prepolymers are prepared (1) having 5 to 60%, preferably at least 35%, of imide moieties, (2) an excess hydroxyl content in excess of 60% and preferably more than 100%, and (3) a number average molecular weight of 600-1300. To water solubilize the prepolymers formed, there are added amines, preferably tertiary amines. The products are useful as wire enamels. To enhance the thermoplastic flow of the enamel, there are added organic titanates.
    Type: Grant
    Filed: May 16, 1979
    Date of Patent: June 3, 1980
    Assignee: Schenectady Chemicals, Inc.
    Inventors: Deno Laganis, Paul M. Begley

  • Water soluble polyester resin
    Patent number: 4133787
    Abstract: Water soluble polyesters are prepared by reacting an aromatic dicarboxylic acid, a diol and a triol (the molar ratio of diol to triol being 75:25 to 40:60) with or without a monohydric alcohol. The polyesters have a molecular weight of 800 to 1300, an OH/COOH ratio of 1.8:1 to 3:1. The polyesters are useful in making wire enamels.
