Patent ID: 6982305

Claim:
A process which comprises polymerizing an olefin in the presence of: (a) a single-site or Ziegler-Natta olefin polymerization catalyst; (b) a low-temperature dehydrogenation catalyst comprising a metal selected from the group consisting of platinum, palladium, rhodium, ruthenium, osmium, iridium, nickel, and rhenium; and (c) an optional hydrocarbon solvent, under conditions effective to promote: (i) olefin polymerization; (ii) catalytic dehydrogenation of the solvent and/or the resulting saturated oligomer or polymer chains to produce short and/or long-chain alkenes; and (iii) copolymerization of additional olefin with the alkenes; to produce a polyolefin having long-chain branching and/or a density less than about 0.96 g/cm 3 .
