A process for for making a cross-linked polyethylene article includes: (A) feeding a blend comprising a cross-linkable silane-group containing polyethylene copolymer and at least one additive to an extruder, (B) feeding a liquid comprising a silanol condensation catalyst to said extruder to form a mixture with said blend, (C) extruding said mixture to form an article and (D) cross-linking said article. The article may be a pipe or cable.

Process for making a cross-linked polyethylene article

The application relates to a process for preparing a crosslinked cable, including:&#x2014;applying one or more layers including a polymer composition on a conductor, wherein at least one layer includes one or more free radical generating agents,&#x2014;crosslinking by radical reaction said at least one layer comprising said free radical generating agent(s),&#x2014;cooling the obtained crosslinked cable in pressurized conditions.
