PRIMARY MIXTURE OF INITIATOR AND PROMOTER OF CROSSLINK

摘要

A primer mixture intended for crosslinking polyethylene, including at least an initiator of free radicals chosen from organic peroxides, azo compounds or mixtures thereof, wherein the mixture has said free-radical initiator and at least one crosslinking promoter chosen from the cycloalkanes having 5 to 7 carbon atoms, substituted by 1 to 3 vinyl, allyl or isopropenyl groups, the aromatic compounds substituted by 1 to 3 vinyl, allyl or isopropenyl groups, the methacrylate, acrylate and maleimide monomers being multi-substituted, and in that the weight ratio of free-radical initiator to the crosslinking promoter is greater than or equal to 1, and preferably between 1.5 and 4. Also, a method and to a use related to this primer mixture.
