Abstract: Copolyetherimide ester thermoplastic elastomers having low modulus can be improved with respect to modulus and tensile properties by incorporation therein of certain effective multistage, rubbery interpolymers comprising a crosslinked (meth) acrylate phase and an interpenetrating, crosslinked styrenic phase.

Abstract: Copolyetherester molding compositions comprising a copolyetherester and a modifying amount of a modulus reducing rubbery interpolymer comprising a crosslinked (meth)acrylate rubbery phase and an interpenetrating, crosslinked styrenic resin phase.

Abstract: Thermoplastic molding compositions are provided which comprise a polyphenylene ether resin alone or in combination with a polystyrene resin modified with a multi-stage polyorganosiloxane/polyvinyl-based graft polymer which exhibit materially enhanced impact strength, flame resistance, moldability and flow properties and other desirable properties without showing surface mottling or a tendancy to delaminate.

Abstract: A resin composition comprising:(i) at least one aromatic carbonate resin;(ii) at least one polyester resin; and(iii) an impact improving effective amount of at least one two-phase interpolymer comprised of at least one cross-linked polyacrylate and at least one cross-linked styrene-acrylonitrile resin.

Abstract: Molding compositions comprise a copolyetherester (A), (B) an aromatic thermoplastic polyester and a multistage rubbery elastomer (C) comprising a crosslinked (meth)acrylate phase and an interpenetrating, crosslinked styrenic phase and optionally, a mineral filler (D). Such compositions are useful for making molded articles with a good balance of modulus and elongation properties.

Abstract: A resin composition comprising:(i) at least one aromatic carbonate resin;(ii) at least one polyester resin; and(iii) an impact improving effective amount of at least one two-phase interpolymer comprised of at least one cross-linked polyacrylate and at least one cross-linked styrene-acrylontrile resin.

Abstract: An aromatic carbonate resin composition substantially free of non-crosslinked or linear styrene-acrylonitrile resin exhibiting improved impact properties comprised of:(i) at least one thermoplastic aromatic carbonate resin; and(ii) an amount effective to improve the impact properties of said resin of at least one interpolymer of a crosslinked polyacrylate and a crosslinked styrene-acrylonitrile resin. The interpolymer is a two phase interpolymer formed by a two stage polymerization process.
