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.
