Abstract:
The present invention relates to polypropylene compositions having a broad molecular weight distribution with a relatively high amount of xylene soluble material. The compositions have an Mw/Mn of five or greater, but preferably greater than 5.5 and more preferably greater than 6.0. The compositions have xylene solubles from 5.0 to 8.0 percent by weight, preferably from 5.5 to 8.0 percent by weight, and more preferably 6.0 to 7.5 percent by weight. The polymers of the present invention are particularly well suited for biaxially oriented polypropylene applications.
