Thermoplastic polyester molding compositions impact-modified by glycidyl methacrylate-grafted EPDM rubbers exhibit improved heat resistance with the addition of glassy polymers, i.e., thermoplastic polymers having amorphous glass transition temperatures above about 100°C, e.g., poly(styrene-acrylonitrile), aromatic poly(sulfone), poly(phenylene ether) and/or aromatic poly(carbonate) without significantly diminishing the impact strength or knit-line characteristics. |
