Abstract:
A metallocene random copolymer of propylene and ethylene in which the ductile/brittle transition temperature of a molded article made from the copolymer may be in the range of from about 20° F. (−7° C.) to about 40° F. (4° C.). The haze level of the molded article may be less than about 10 percent for an 80-mil (0.2 cm) thick plaque. The metallocene random copolymer may further include a clarifier.
