Abstract
Siloxane cross-linking of polyethylene is carried out under in situ development of water by chemical reaction between an organic acid and a non-hygroscopic metal oxide producing a neutral salt and water. Specifically, an ester peroxide is used as additive to be mixed with silane and polyethylene. The ester peroxide decomposes during grafting in free acid, alcohol and graft initiators for obtaining the grafting of silane on polyethylene, and the acid reacts with zinc oxide or tin oxide, also used as additive, to obtain salt and water. Alternatively, stearic acid or adipic acid and zinc oxide or tin oxide are added to a polyethylene silane mixture to develop water and salt of the acid.
