Abstract:
A linear, homogeneous copolymer comprising alpha-olefin and divinylbenzene comonomer units, and having the structural formula: wherein R is a member selected from the group consisting of linear and branched alkyl groups and cyclic aliphatic and aromatic groups; x is the mole % of ethylene-derived units in the copolymer; y is the mole % of alpha-olefin-derived units in the copolymer, other than ethylene-derived units; x+y is the combined alpha-olefin mole % in the copolymer and is between about 50 to 99.9%; z is the mole % of units in the copolymer that are derived from divinylbenzene; and the sum of x+y+z is 100%; said copolymer having a ratio of total unsaturation/divinylbenzene (TUS/DOU) from 0.8 to 1.1, a number average molecular weight (Mn) of at least 1,000, and a ratio of weight average molecular weight to number average molecular weight (Mw/Mn) of less than 4; and wherein said divinylbenzene comonomer units are derived from a divinylbenzene selected from the group consisting of 1,4-divinylbenzene, mixtures of 1,4-divinylbenzene and 1,3-divinylbenzene, and mixtures of 1,4-divinylbebzene, 1,3-divinylbenzene and 1,2-divinylbebzene.
