Abstract

Low molecular weight, highly branched polyolefins are provided. Also provided are catalyst-mediated methods of making the low molecular weight, highly branched polyolefins and a catalyst system for carrying out the methods. The catalyst system is a homogeneous catalytic system that includes a single-site organozirconium complex and hydrocarbon-soluble perfluoroarylborate co-catalyst that is highly active for the oligomerization of olefin monomers in non-polar media.
