This invention relates to a vinyl terminated higher olefin copolymer having an Mn of 300 g/mol or more (measured by 1H NMR) comprising: (i) from about 20 to about 99.9 mol % of at least one C5 to C40 higher olefin monomer; and (ii) from about 0.1 to about 80 mol % of propylene; wherein the higher olefin copolymer has at least 40% allyl chain ends. The copolymer may also have an isobutyl chain end to allyl chain end ratio of less than 0.7:1 and/or an allyl chain end to vinylidene chain end ratio of greater than 2:1.
