Abstract

A process for manufacturing a polyolefin powder having a thermoplastic elastomer includes the steps of

combining a polyolefin powder or a monomeric source therefor with a thermoplastic elastomer, the thermoplastic elastomer being in the form of a solution or dispersion in a solvent,wherein where a monomeric source of a polyolefin is used, contacting the source of a polyolefin with a polymerization catalyst under polymerization conditions to form a polyolefin, andremoving the solvent to form a powderand wherein the polyolefin and the thermoplastic elastomer are not the same polymer. A particulate polyolefin composition which has a particle size distribution such that at least 80 vol. % of the particles has a diameter in the range of 1-3000 microns, and which includes a nascent polyolefin and 0.1-30 wt. % of a thermoplastic elastomer, calculated on the total of polyolefin and thermoplastic elastomer, is also described.
