Patent ID: 8846991

Claim:
A homogeneous, liquid, low molecular weight ethylene/octene copolymer, wherein the copolymer consists essentially of polymerized ethylene and 1-octene monomeric units, and wherein greater than 95 percent of the copolymer's short chain branches are hexyl branches, and wherein the copolymer has the following properties: a) a number average molecular weight (Mn), as determined by gel permeation chromatography, of less than 25,000; b) a total crystallinity, as measured by DSC, of less than 10%; c) a pour point, as measured by ASTM D97, of less than 50° C., and wherein the polymer is prepared in the presence of a constrained geometry catalyst, of the Formula III: wherein: M is titanium, zirconium or hafnium, bound in an η 5 bonding mode to the cyclopentadienyl group; R′ each occurrence is independently selected from the group consisting of hydrogen, silyl, alkyl, aryl, and combinations thereof, having up to 10 carbon or silicon atoms; E is silicon or carbon; X independently each occurrence is hydride, halo, alkyl, aryl, aryloxy or alkoxy of up to 10 carbons; m is 1 or 2; and n is 1 or 2 depending on the valence of M.
