A composition that may be useful for thermoforming and blow molding applications comprises a metallocene catalyzed propylene-ethylene random copolymer having an ethylene content of from about 0.1 to about 1.5 weight percent based on the copolymer, and exhibits a flexural modulus of at least about 1,100 MPa, a haze of less than about 40 percent, a melt flow of from about 1.0 dg/min to about 3.0 dg/min, and a xylene solubles content from about 0.2 weight percent to about 1.0 weight percent based on the copolymer. A process for preparing the copolymer and articles prepared therefrom are also disclosed. The composition's properties may make it particularly desirable for applications such as bottles, syringes and containers such as those used for food and medical purposes.
A composition comprising a metallocene catalyzed propylene-ethylene random copolymer having an ethylene content of from about 0.1 to about 1.5 weight percent based on the copolymer, a flexural modulus of at least about 1,100 MPa, a haze of less than about 40 percent for a 40-mil thick sheet, a melt flow of from about 1.0 dg/min to about 3.0 dg/min, and a xylene solubles content from about 0.2 weight percent to about 1.0 weight percent based on the copolymer.
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 copolymer having a flexural modulus of at least about 1,100 MPa, a haze of less than about 40 percent for a 40-mil thick sheet, a melt flow of from about 1.0 dg/min to about 3.0 dg/min, and a xylene solubles content from about 0.2 weight percent to about 1.5 weight percent based on the copolymer.
An article of manufacture prepared from a composition comprising a metallocene catalyzed propylene-ethylene random copolymer having an ethylene content of from about 0.1 to about 1.5 weight percent based on the copolymer;
