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

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.

Impact-improved polyphenylene ether resin compositions which also exhibit improved melt behavior without degradation of other themal properties are provided by combining a polyphenylene ether polymer, an alkyl or aralkyl sulfonate of an alkali metal, where the alkyl or aralkyl radical has 5 to 25 carbon atoms, and an acrylate-styrene-acrylonitrile terpolymer.

Polyphenylene compositions having improved melt behavior and impact

Polyphenylene ether resin compositions exhibiting improved melt behavior without degradation of other thermal properties are provided by combining a polyphenylene ether polymer and an alkyl or aralkyl sulfonate of an alkali metal, where the alkyl or aralkyl radical has 5 to 25 carbon atoms.
