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.

Disclosed herein are methods of preparing an aminimide. An epoxy compound is reacted with a hydrazine compound comprising a trivalent nitrogen, and an anhydride functional material or a cyclic compound containing a carbonyl group and at least one heteroatom alpha to the carbonyl group at a temperature greater than 20 C. to form the aminimide.
