Abstract:
1. A polyester composition comprising: I. about 70 to about 97.5 weight percent of a thermoplastic polyester comprising poly(ethylene terephthalate) having an intrinsic viscosity of about 0.55 to 1.1 dL/g, measured at 25° C. in a solvent consisting of 60 weight percent phenol and 40 weight percent tetrachloroethane; II. about 2 to about 25 weight percent of an impact modifying polymer comprising one or more ethylene/methyl acrylate/glycidyl methacrylate terpolymers containing about 20 to 35 weight percent methyl acrylate residues and about 2 to 10 weight percent glycidyl methacrylate residues and mixtures of the terpolymers with up to 50 weight percent of an ethylene/methyl acrylate copolymer containing about 20 to 35 weight percent methyl acrylate residues; and III. about 0.5 to about 5 weight percent of a block copolymer of poly(tetramethylene terephthalate) and poly(oxytetramethylene)diol wherein wherein the weight percentages of I, II and III are based on the total weight of components I, II and III.
