  • Polyphenylene ether/siloxane polyetherimide copolymer
    Patent number: 5280085
    Abstract: Polymer blends contain a polyphenylene ether and a siloxane-polyetherimide copolymer. These blends exhibit good ductility, good injection moldability, very low flammability and high impact strengths.
    Type: Grant
    Filed: November 25, 1991
    Date of Patent: January 18, 1994
    Assignee: General Electric Company
    Inventors: John A. Rock, Norman E. Durfee, Jr., L. Joseph Male
  • Flame resistant polyetherimide resin blends
    Patent number: 5106915
    Abstract: Flame resistant polymer blends contain a polyetherimide and an impact strength-enhancing amount of a siloxane-polyetherimide copolymer. These blends exhibit high impact strengths, good blow-moldability and injection moldability, amenability to thermoforming and very low flammability. The blends are particularly suited to the manufacture of aircraft cabin interior components.
    Type: Grant
    Filed: August 8, 1991
    Date of Patent: April 21, 1992

    Inventors: John A. Rock, L. Joseph Male, Norman E. Durfee, Jr.
  • Flame resistant polyetherimide resin blends
    Patent number: 5051483
    Abstract: Flame resistant polymer blends contain a polyetherimide and an impact strength-enhancing amount of a siloxane-polyetherimide copolymer and a solvent resistance-enhancing amount of a polycarbonate. These blends exhibit excellent impact strengths, high heat distortion temperatures, good solvent resistance, and amenability to blow-molding, injection molding and thermoforming operations. The blends are particularly suited to the manufacture of aircraft cabin interior components.
