POLYESTER COMPOSITIONS ABSTRACT Poly(C2-C4 alkylene terephthalate) molding composition containing aromatic polyester and impact modifier. The aromatic polyester is a linear aromatic polyester consisting essentially of bisphenol and dicarboxylic acid monomer components. 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 C1-C6 alkylacrylate as well as crosslinking and graftlinking monomers and having a final rigid thermoplastic phase polymerized in the presence of the elastomeric phase.
