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.

Polyetherimide ester elastomeric compositions

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.

Copolyetherester elastomeric compositions

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.

Polyphenylene ether or polyphenylene ether/polystyrene with

Resin blends exhibiting improved impact properties

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.

An aromatic carbonate resin composition substantially free of non-crosslinked or linear styrene-acrylonitrile resin exhibiting improved impact properties comprised of:
