Abstract
Poly(C.sub.2 -C.sub.4 alkylene terephthalate) molding composition containing aromatic polyester carbonate and impact modifier. The aromatic polyester carbonate is derived from a dihydric phenol, a carbonate precursor and dicarboxylic acid or ester forming derivative thereof. The impact modifier may be a core-shell polymer polymerized from monomers comprising butadiene or may be a core-shell polymer having a first elastomeric phase polymerized from a monomer system including C.sub.1 -C.sub.6 alkylacrylate as well as crosslinking and graftlinking monomers and having a final rigid thermoplastic phase polymerized in the presence of the elastomeric phase.
