Abstract:
1. A process for preparing a composition comprising contacting propylene and ethylene monomers and a metallocene catalyst under reaction conditions suitable to form a random propylene-ethylene copolymer having an ethylene content of from about 0.1 to about 1.5 weight percent based on the copolymer, the composition having a flexural modulus of at least about 1,100 MPa, and a haze of less than about 40 percent for a 40-mil thick sheet as measured by ASTM D1003:2000; and the copolymer having a melt flow of from about 1.0 dg/min to about 3.5 dg/min as measured by ASTM D1238:2000, and a xylene solubles content of from about 0.2 weight percent to about 1.5 weight percent based on the copolymer.
