摘要 |
A power cable coating composition comprising a copolymer of ethylene, or ethylene and an alpha -olefin, with 0.02-2 mol-% of a cyclic non-conjugated diene, said copolymer being prepared by a high-pressure radical polymerization process, said copolymer having a melt index of 0.2-10 g/10 min and an iodine value in the range of 0.2 to 20, and not more than 2.5 parts by weight, based on 100 parts by weight of said copolymer, of a peroxide, said composition on heat-crosslinking affording a crosslinked product having at least the following properties:
a) a percent heat-deformation at 120 DEG C not more than 20%, and
b) a maximum peak temperature (Tm) not lower than 100 DEG C measured according to the differential scanning calorimetry (DSC). |
