Abstract

The invention concerns an unsaturated ethylene copolymer, a method for producing it, and the use thereof for producing cross-linked structures, such as insulating layer material, semiconductor layer material and sheath material for electric cables. The unsaturated ethylene copolymer comprises a polymer obtained by radical polymerisation through a high-pressure process of ethylene and at least one monomer which is copolymerisable with ethylene and includes a diunsaturated comonomer of the formula (I): H2C = CH-O-R-CH = CH2 wherein R = -(CH2)m-O-, -(CH2CH2O)n-, or -CH2-C6H10-CH2-O-, m = 2-10 and n = 1-5. Preferably, the comonomer of formula (I) is 1,4-butanediol divinyl ether.
