  • Novel polymers of olefin terminated prepolymers and amine terminated prepolymers
    Patent number: 4266047
    Abstract: New and useful polymers are prepared by reacting olefin-terminated prepolymeric materials with simple polyamine, by reacting simple olefins with amine-terminated prepolymers and by reacting olefin-terminated prepolymers with amine-terminated prepolymers. The new and useful polymeric materials so obtained can be cured as with heat, with or without catalyst, to provide products useful for preparing films, laminates, composites, prepregs, molding materials, varnishes, wire enamels and the like.
    Type: Grant
    Filed: December 13, 1976
    Date of Patent: May 5, 1981

    Inventors: Richard J. Jablonski, Daniel Kruh
  • Process of breaking up gel of polyamide-imide
    Patent number: 4182853
    Abstract: New and useful polyamideimide polyamines are disclosed which are used to prepare polyamideimide amic acids and polyamideimideimides useful as films, coatings and adhesives.
    Type: Grant
    Filed: October 3, 1973
    Date of Patent: January 8, 1980
    Assignee: General Electric Company
    Inventor: Daniel Kruh
  • Process of preparing maleimides
    Patent number: 4122076
    Abstract: Imide group containing solutions are prepared by reacting the Diels-Alder reaction product of furan and maleic anhydride with amine, heating the resultant amic acid to form the maleimide material with regeneration of furan. The imide-containing products can be isolated.
