ABSTRACT:
Disclosed herein is a process for producing cross-linked polypropylene by subjecting a homogenous mixture of a polypropylene with from about 2 to about 20 weight percent, based upon the weight of the polypropylene, of polybutadiene with a molecular weight of from about 500 to about 10,000 to conditions sufficient to effect cross-linking, for example, through the use of cross-linking agents and/or irradiation. In addition, the process disclosed herein may be utilized to produce cross-linked and foamed polypropylenes.
