Abstract
Articles of manufacture and a method of making the articles are provided. The articles of manufacture comprise CpFlu metallocene catalyzed polypropylene homopolymers and C2–C3 random copolymers having narrow molecular weight distributions and low xylene solubles (or extractables) contents. Because of a number of desirable properties, the polypropylene homopolymers and C2–C3 random copolymers may be used to prepare a wide variety of useful articles, including but not limited to cast films, such as packaging; fibers suitable for use in fabrics and carpet applications, and injection and blow molded items such as bottles.
