A moldable polymer composition comprising an acetophenone based bisphenol polyarylate resin and a monovinyl aromatic/N-arylmaleimide copolymer is disclosed. In one embodiment, the N-arylmaleimide containing copolymer is rubber modified by the incorporation of an elastomeric polymer during the formation of the copolymer. In another embodiment, the moldable polymer composition is rubber modified by the incorporation of an elastomeric polymer using any conventional method of blending.

Acetophenone based bisphenol polyarylate resins

A composition of matter which comprises an elastomer grafted at a level of from about 40 to about 60 weight percent with a polymer matrix comprising recurring units of at least one free radical polymerizable monomer and its method of preparation are disclosed.

Elastomer grafted with polymer matrix and method

An extrudable acrylic composition which incorporates an interpolymer produced by the polymerization of methyl methacrylate monomer, an N-substituted maleimide monomer, an alkyl acrylate monomer, and a difunctional reactive monomer is disclosed.

Thermoplastic interpolymers of methyl methacrylate, N-substituted

Polymer alloys containing copolymers of methylmethacrylate/N-phenylmaleimide are disclosed. In one embodiment the polymer alloy is an alloy of methylmethacrylate/N-phenylmaleimide and styrene/maleic anhydride. In another embodiment, the polymer alloy is an alloy of methylmethacrylate/N-phenylmaleimide and styrene/maleic anhydride/N-phenylmaleimide.

Methylmethacrylate/phenylmaleimide copolymer and styrene/maleic

An A-B-A triblock copolymer particularly suitable for use as an impact modifier for thermoplastic molding compositions containing an imide containing copolymer is disclosed. Molded compositions of the invention exhibit excellent impact strength and heat resistance and are transparent.
