| 摘要 |
The invention provides an unsaturated low density polyethylene (LDPE) selected from homopolymer or copolymer of ethylene and one or more polyunsaturated comonomers and, optionally with one or more other comonomers, which has a) a melt flow rate, MFR, of at least 2.8 g/10 min, and b) carbon-carbon double bonds in an amount of at least 0.40 carbon-carbon double bonds/1000 carbon atoms. A polymer composition comprising an unsaturated low density polyethylene and a crosslinking agent, an article which is a cable or a wire comprising said unsaturated low density polyethylene or a polymer composition and also a process for producing said cable. Said unsaturated low density polyethylene and polymer composition can be used in producing a cable or a wire, preferably crosslincable, providing excellent processability properties, including flowability, without causing or increasing sagging problems. |
