Abstract

A process for crosslinking a polyolefin that is polyethylene, an ethylene copolymer with up to 10 mole percent of one or more of the compounds propylene, butene 1 and hexene 1. Or an ethylene copolymer with up to 50 percent in moles of vinyl acetate or ethyl acrylate, comprising (A) reacting said polylefin with a silane of the general formula RR'SiY2, in which R represents an olefinically unsaturated monovalent radical bound to silicon through a silicon bond -carbon, and is composed of carbon, hydrogen and optionally, oxygen, each Y represents a hydrolyzable organic radical and R'' represents a monovalent hydrocarbon radical free of aliphatic unsaturation or a hydrolyzable organic radical, in the presence of a free radical generating compound which is a compound of the general formula R''COOR''', in which R''` represents a secondary or tertiary alcohol radical, a cycloalcohyl radical which it has more than 4 carbon atoms, or a benzyl radical and R'''represents a tertiary alcohol radical or a cumyl radical, said reaction being carried out at a temperature at which the free radical generating compound has a half-life of less than 6 minutes, and (B) subsequently exposing the product of (A) to the action of water in the presence of a silanol condensation catalyst.
