Abstract

This invention relates to a process to make a multimodal polyolefin composition comprising: (i) contacting at least one first olefin monomer with a mixed catalyst system, under polymerization conditions, to produce at least a first polyolefin component having a Mw of 5,000 g/mol to 600,000 g/mol, wherein the mixed catalyst system comprises: (a) at least one polymerization catalyst comprising a Group 4 or Group 5 transition metal; (b) at least one organochromium polymerization catalyst; (c) an activator; and (d) a support material; (ii) thereafter, contacting the first polyolefin component/mixed catalyst system combination with a molecular switch; (iii) contacting the first polyolefin component/mixed catalyst system combination with at least one second olefin monomer, which may be the same or different, under polymerization conditions; and (iv) obtaining a multimodal polyolefin composition.
