Klementina F. Khait has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • High impact polyphenylene ether compositions having improved processability
    Patent number: 4491649
    Abstract: Polyphenylene ether resins impact modified with a rubbery impact modifier such as an ABA block copolymer or a polyolefin is made more processable by further compounding with a moderate amount of an aromatic polycarbonate. The compositions exhibit markedly high impact strength and high heat distortion temperature characteristics.
    Type: Grant
    Filed: December 1, 1983
    Date of Patent: January 1, 1985
    Assignee: Borg-Warner Chemicals, Inc.
    Inventors: John C. Falk, Ronald L. Jalbert, Klementina F. Khait
  • Phenylene ether copolymer aromatic polycarbonate blends
    Patent number: 4485219
    Abstract: Blends comprising an aromatic polycarbonate and a phenylene ether copolymer resin exhibiting good toughness and improved high temperature end-use performance as measured by heat distortion temperature.
    Type: Grant
    Filed: December 1, 1983
    Date of Patent: November 27, 1984
    Assignee: Borg-Warner Chemicals, Inc.
    Inventors: John C. Falk, Klementina F. Khait
  • Glass-filled thermoplastic resins
    Patent number: 4414342
    Abstract: Glass fiber reinforced thermoplastic resins composing glass fiber, a thermoplastic resin and a copolymer of an ethylenically-unsaturated monomer and from about 1 to about 20 wt. % of copolymerizable functional monomer exhibit a marked improvement in impact properties, heat distortion values and ductility, and improved adhesion between matrix resin and fiber.
    Type: Grant
    Filed: December 7, 1981
    Date of Patent: November 8, 1983
    Assignee: Borg-Warner Corporation
    Inventors: John C. Falk, Klementina F. Khait
  • Method for molding glass-filled thermoplastic resins
    Patent number: 4402902
    Abstract: Glass fiber reinforced thermoplastic resins comprising glass fiber, a thermoplastic resin and a copolymer of an ethylenically-unsaturated monomer and from about 1 to about 20 wt. % of copolymerizable functional monomer exhibit a marked improvement in impact properties when melt processed in screw-fed melt processing equipment such as a screw-fed injection molding machine using back-pressures in the range 0-100 psi.
