  • Polyetherimide-polycarbonate blends
    Patent number: 4548997
    Abstract: Disclosed are blends of (a) a polyetherimide and (b) a thermoplastic polycarbonate. The blends exhibit a higher heat distortion temperature and an improved flexural strength and tensile strength over the polycarbonate component alone and have a higher impact strength than that associated with the polyetherimide component of the blends. In addition, the blends may exhibit good flame resistance.

  • Polyetherimide-polysulfide blends
    Patent number: 4455410
    Abstract: Disclosed are blends of (a) a polyetherimide and (b) a polysulfide. The blends have good flexural strength regardless of the relative proportions of the components of the blend and have generally higher mechanical properties than those associated with the polysulfide component of the blend.

  • Polyetherimide-fluorinated polyolefin blends
    Patent number: 4433104
    Abstract: Disclosed are blends of (a) a polyetherimide and (b) a thermoplastic fluorinated polyolefin, or copolymer thereof. The blends have good flexural strength and flexural modulus and have a higher impact strength than those associated with the polyetherimide components of the blends.

  • Polyetherimide-polypropylene blends
    Patent number: 4427830
    Abstract: Disclosed are blends of (a) a polyetherimide and (b) a minor amount, e.g., about 1 to about 20 weight %, of polypropylene or copolymer thereof. Unexpectedly, these blends have a higher notched Izod impact strength than that associated with the polyetherimide component of the blends and those associated with other polyetherimide-polypropylene blends which do not contain a minor amount of polypropylene.

  • Polyetherimide-acrylate copolymer blends
    Patent number: 4395518
    Abstract: Disclosed are blends of (a) a polyetherimide and (b) a minor amount of an acrylate copolymer of C.sub.1 -C.sub.5 acrylate and C.sub.1 -C.sub.5 methacrylate. These blends have a higher impact strength than that associated with the polyetherimide component of the blends. In addition, the blends exhibit improved extrusion and molding performance characteristics over those of the polyetherimide component of the blend when molded alone.

  • Blends of polyetherimides and rubber modified vinyl aromatic polymers
    Patent number: 4393168
    Abstract: Disclosed are blends of (a) a polyetherimide and (b) a rubber modified vinyl aromatic polymer. Depending upon the particular rubber modified vinyl aromatic polymer used in preparing the blends, one or more of the properties of impact strength, heat distortion temperature, flexural properties and tensile properties of the blends are improved over those associated with the polyetherimide component alone or with the rubber modified vinyl aromatic polymer alone.

  • Polyetherimide-EPDM terpolymer blends
    Patent number: 4390665
    Abstract: Disclosed are blends of (a) a polyetherimide and (b) a minor proportion of an EPDM terpolymer. Among other things, these blends have a higher impact strength throughout the range of normal operating temperatures than that associated with the polyetherimide component of the blends.

  • Blends of polyetherimides and organopolysiloxane-polycarbonate block copolymers
    Patent number: 4387193
    Abstract: Disclosed are blends of (a) a polyetherimide and (b) an organopolysiloxane - polycarbonate block copolymer. Such blends exhibit a good combination impact strength and flexural properties particularly at relatively high proportions of polyetherimide, and elastomeric behavior at relative high concentrations of the block copolymer of organopolysiloxane and polycarbonate.
