A CROSSLINCABLE POLYETHYLENE COMPOSITION, AN ELECTRIC CABLE COMPRISING IT, AND A PROCESS FOR ITS PREPARATION

摘要

A crosslinkable silane containing polyethylene composition, an insulated electric cable, and a process for the preparation of the composition are described. The crosslinkable silane containing polyethylene composition has a silane content of about 0.1 to 10 % by weight, and at least one silanol condensation catalyst, and is characterised in that the composition has a branching parameter (g') value of at least 0.65. The insulation of the electrical cable comprise the composition as a polymer. The process is characterised in that it is a high pressure polymerisation process at a peak temperature of at most 260°C.
