  • Cure retarding additives for acetylene-terminated polymers
    Patent number: 4381363
    Abstract: A polymeric composition comprised of a mixture of an acetylene-terminated polymer and an hydroxy-substituted, polynuclear, aromatic derivative as a cure retarding additive.
    Type: Grant
    Filed: September 10, 1981
    Date of Patent: April 26, 1983
    Assignee: The United States of America as represented by the Secretary of the Air Force
    Inventor: Theodore J. Reinhart, Jr.
  • Acetylene-terminated polyimide compositions
    Patent number: 4365034
    Abstract: A composition of matter comprising an acetylene-terminated polyimide oligomer and a cure rate inhibitor selected from the group consisting of hydroquinone, maleic acid, glutaric acid, dibetanapthyl para-phenylene diamine. The composition has a retarded cure rate, thereby facilitating the fabrication of void-free molded objects and composites.
    Type: Grant
    Filed: September 21, 1981
    Date of Patent: December 21, 1982
    Assignee: The United States of America as represented by the Secretary of the Air Force
    Inventors: Mark F. Grimes, Theodore J. Reinhart, Jr.
  • Water based oligomeric primers for aluminum and aluminum alloys
    Patent number: 4238379
    Abstract: A primer, particularly for aluminum and aluminum alloys, that is free of alkaline materials and consists essentially of an aqueous solution of a water soluble condensation product of (1) phenol, resorcinol or a mixture of phenol and resorcinol and (2) formaldehyde.
    Type: Grant
    Filed: May 29, 1979
    Date of Patent: December 9, 1980
    Inventor: Theodore J. Reinhart, Jr.
  • Acetylene-terminated polyimide compositions
    Patent number: 4187359
    Abstract: A composition of matter comprising an acetylene-terminated polyimide oligomer and trinitriloacetonitrile. The composition has a retarded cure rate, thereby facilitating the fabrication of void-free molded objects and composites.
    Type: Grant
    Filed: December 6, 1978
