The present invention provides an ethylene copolymer comprising 85.0 to 99.995 mol% of ethylene units, 0.005 to 5 mol% of a comonomer unit represented by the formula (I)n nwherein Ar isn n R, is a hydrogen atom or a methyl group, each of R 2 and R 3 is a hydrogen atom, a chlorine atom or a straight-chain or a branched alkyl group having 1 to 4 carbon atoms, nand 0 to 10 mol% of units of an ethylenically unsaturated monomer, the ethylene copolymer having a density of 0.860 to 0.970 g/cm 3 and a melt index of 0.05 to 100 g/10 minutes. |
