Abstract
Thermoplastic polyester, copolyester and polyblend molding compositions impact-modified by glycidyl methacrylate grafted EPDM exhibit high impact strength combined with good knit-line characteristics, when the grafted comonomer content exceeds 2 percent by weight in the impact modifier, it has a gel content in the range of from about 10 to about 80 weight percent.
