ABSTRACT:
A modified supported olefin polymerization catalyst modified by prepolymerization with an olefin or an olefin mixture different from the olefin or olefin mixture of the subsequent olefin polymerization. The polymerization catalyst is a metallocene, and the melting or softening point of the polyolefin made using the catalyst is at least 20° C. lower than that of the prepolymerized polyolefin.
