Abstract: A copolymer including ethylene units and units of one or more C3-10 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.
