A crosslinkable polymer composition includes an unsaturated polyolefin having a total amount of carbon-carbon double bonds/1000 carbon atoms of at least 0.1, at least one scorch retarder, and at least one crosslinking agent.

Scorch-retarding polymer composition

A Polymer Composition comprising at least one unsaturated polymer, and optionally a crosslinking agent.

Crosslinkable polymer composition

The invention relates to a semiconductive polymer composition for use in power cables. The composition comprises a multimodal ethylene homo- or copolymer produced in a polymerization process comprising a single site catalyst whereby the polymer composition has a density of 870 to 930 kg/m3, a MFR2 of 1 to 30 g/10 min and a Mw/Mn of less than or equal to 10.

Semiconductive polymer composition

The present invention relates to a semiconductive polymer composition comprising an olefin homo- or copolymer wherein the composition has a direct current volume resistivity of less than 1000 Ohm&#xb7;cm at 90&#xb0; C., an elongation at break which after aging for 240 hours at 135&#xb0; C. does not change by more than 25%, and a total number of structures of 20 or less in the SIED test. Furthermore, the present invention relates to an electric power cable comprising a conductor, a semiconducting layer and, adjacent to the semiconducting layer, an insulation layer, wherein the semiconducting layer is formed by said semiconductive polymer composition and to the use of said semiconducting polymer composition for the production of a semiconductive layer of an electric power cable.

Semiconductive polymer compositions
