Abstract: A process for preparing an ethylene copolymer in the presence of free-radical polymerization initiator at pressures from 150 MPa to 350 MPa and temperatures from 100° C. to 350° C., by copolymerizing ethylene and a comonomer having a C≡C bond and optionally further comonomers, wherein the comonomer having the C≡C bond is represented by formula wherein R1 is hydrogen or methyl; X1 is —CO—O— or —CO—NH—; R2 is —CH2—O—, —O—CO—, —Si(CH3)2—, —Si(CH3)2—O— or —CR5R6— wherein R5 and R6 are independently selected from hydrogen, methyl, ethyl and hydroxyl; n is an integer from 1 to 32 and R2 is same or different from each other when n is 2 to 32; and R3 is —C≡C— and R4 is hydrogen, C1-C10 linear or branched alkyl, C1-C10 linear or branched hydroxyalkyl or phenyl, or the unit R3-R4 stands for wherein X2 is F, Cl, Br or I.
