Abstract
Novel thermoplastic polyester compositions having improved impact behavior are produced. These compositions comprise a blend of poly (C.sub.2 -C.sub.4 alkylene terephthalate) with certain low molecular weight diepoxide resins, a triphenyl phosphonium halide catalyst, and a multiphase composite polymer. The multiphase polymer has a first elastomeric phase polymerized from a monomer system including butadiene or butadiene/styrene and a final rigid thermoplastic phase polymerized in the presence of the elastomeric phase.
