Abstract:
A copolymer including ethylene units and units of one or more C 3-10  alpha-olefins. The copolymer has a number average molecular weight of less than 5,000 g/mol, as measured by GPC. The copolymers have low metal (ash) and/or fluorine contents.The ethylene content of the copolymer is less than 80 mol %. 70 mol % or greater of the copolymer has a carbon-carbon double bond in a terminal monomer unit, and at least 70 mol % of the terminal monomer units that have a carbon-carbon double bond have a terminal group selected from a vinylidene group and a tri-substituted isomer of a vinylidene group. The copolymer has a crossover temperature of −20° C. or lower and/or a certain ethylene run length. Also disclosed are a method for making the copolymer and polyolefins plasticized with 1-40 wt. % of the copolymer as well as methods of fanctionalizing the copolymer and products made with the functionalized coploymer.

Claim (Index 20):
The copolymer of  claim 1 , wherein:\n (a) the ethylene content of the copolymer is at least 10 mol % and less than 70 mol %, (b) the C 3 -C 10  alpha-olefin content of the copolymer is at least 40 mol % of propylene, (c) at least 85 mol % of the copolymer terminates in the terminal vinylidene group or the tri-substituted isomer of the terminal vinylidene group, (d) the copolymer has an average ethylene unit run length of less than 2.4. (e) the crossover temperature of the copolymer is \u221230\u00b0 C. or lower. (f) the copolymer of  claim 1 , wherein the copolymer has a polydispersity index of less than or equal to 4, (g) the number average molecular weight of the copolymer is between 800 and 4,000 g/mol, as measured by GPC, and (h) less than 20% of unit triads in the copolymer are ethylene-ethylene-ethylene triads.
