Abstract

The present invention provides a process for producing a polyethylene composition by treating a cross-linkable ethylene copolymer containing monomer units with hydrolysable silane-groups and polar monomer units. The invention further provides a treated cross-linkable polyethylene composition 5 obtained by the process and a silane-crosslinked polyethylene composition obtained by the process. The invention further provides articles comprising the treated cross-linkable polyethylene composition or comprising the silane-crosslinked polyethylene composition.
