Abstract:
1. A polymer comprising units ( 1 ) derived from an aipha-olefin having at least 3 carbon atoms ( 1 ′), units ( 2 ) derived from divinylbenzene or C 1-10 hydrocarbyl substituted derivatives thereof ( 2 ′), and units ( 3 ) derived from ethylene ( 3 ′), the polymer comprising at least 75 mole % of units ( 1 ), from 0.01 to 5 mole % of units ( 2 ), and up to 20 mole % of units ( 3 ), the polymer having a branching factor BF≦0.75, factor BF representing the ratio D/(A+B) wherein D, A, and B are integrated signal values determined by quantitative carbon-13 NMR spectroscopy of the polymer wherein A represents the integrated value of the signals in the range of 145.0 to 142.5 ppm, B represents the integrated value of the signals in the range of 142.5 to 139.0 ppm, and D represents the integrated value of the signals in the range of 115.0 to 112.5 ppm.
