Abstract
A polypropylene composition comprises an isotactic polypropylene homopolymer resin that is suitable to form an injected molded article exhibiting less than about 60% haze, as determined by ASTM D1003, at a thickness of 0.05 inch without clarity-enhancing agents. The polypropylene composition has particular application to injection molded articles and may have a melt flow rate of from about 0.1 g/10 min to about 150 g/10 min as determined by ASTM D-1238, Procedure B. The resin may be prepared using a metallocene catalyst, and the composition may include clarity-enhancing agents for even greater clarity improvements.
