Abstract
A method of producing a silane cross-linked polyethylene is disclosed which includes maleating a polyethylene polymer to form a maleated polyethylene and reacting the maleated polyethylene with a primary or secondary amino silane to form a silane-grafted polyethylene. The method further includes treating the silane-grafted polyethylene in a moisture curing process to form the silane cross-linked polyethylene.
