  • Polyamide-imide composition based on bisphenoxyphenyl diamines
    Patent number: 4981942
    Abstract: Polyamide-imide compositions, including amic acid precursors thereto, having in their molecules recurring units based on aromatic tri- and tetracarbonyl moieties joined by a bisphenoxyphenyl structure exhibit a desirable combination of chemical, mechanical and thermal properties and retention of these properties on exposure to elevated temperatures even after saturation with water.
    Type: Grant
    Filed: July 13, 1989
    Date of Patent: January 1, 1991
    Assignee: Amoco Corporation
    Inventors: Ronald E. Bockrath, Bill W. Cole

  • Continuous fiber inserts for injection molded parts
    Patent number: 4600617
    Abstract: A process for incorporating continuous graphite fiber reinforcement impregnated with polyamide-imide polymer onto injection molded polyamide-imide parts. These impregnated parts are useful as automotive parts such as push rods or rocker arms, and for aircraft parts such as fittings and secondary structural parts.
    Type: Grant
    Filed: April 27, 1984
    Date of Patent: July 15, 1986
    Assignee: Standard Oil Company (Indiana)
    Inventor: Bill W. Cole
  • Laminates
    Patent number: 4579773
    Abstract: Novel fiber fabric laminates impregnated with polyamide-imide and polyamide-imide-phthalamide copolymers are disclosed. The laminates are useful as engineering materials for the replacement of metals.
    Type: Grant
    Filed: August 20, 1984
    Date of Patent: April 1, 1986
    Assignee: Standard Oil Company (Indiana)
    Inventors: Bill W. Cole, Gary T. Brooks
  • Injection moldable amide-imide polymers and copolymers containing semi-crystalline and amorphous polyamides
    Patent number: 4515924
    Abstract: Flow properties of polyamide-imide polymers are improved by the addition of semi-crystalline nylons or amorphous polyamides. These polymers are useful as engineering resins, laminates, and molded objects.
