ABSTRACT:
A thermoplastic elastomeric polypropylene (and other olefin homopolymerized polymers) using a novel catalyst with a single monomer olefin, and method of preparing the same to produce a chain of alternating stereo regular crystallizable segments and stereo-irregular non-crystallizable polymerized segments, the former acting as physical crosslinks between the non-crystallizable segments to form a thermoplastic elastomeric material having good elastomeric properties.
