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.

High impact polyphenylene ether compositions having improved

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.

Phenylene ether copolymer aromatic polycarbonate blends

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.

Glass-filled thermoplastic resins

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.
