Abstract

An ethylene copolymer having at least one comonomer selected from: (a) <alpha>-olefins of the formula CH2=CH-CH2R, in which R is hydrogen or a linear, branched or cyclic alkyl having 1 to 20 carbon atoms; (b) cycloolefins; and (c) polyenes; with a content of ethylene units of between 80 and 99 mol%, a content of units derived from <alpha>-olefin, cycloolefin and/or polyene comonomers of between 1 and 20 mol%, characterized in that: (a) in TREF (Temperature Rising Elution Fractionation) analysis, a quantity equal to at least 90% by weight of the copolymer is eluted within a temperature interval of less than 50 DEG C, and (b) Mw/Mn > 3, where Mw is the weight-average molecular weight and Mn is the number-average molecular weight, both determined by means of GPC.
