    Abstract: PURPOSE:To conduct crosslinking effectively, by feeding an extruder with a polyolefin, a silane compound and a radical-generating agent, extruding the mixture, coating the surface of the extrudate with a colorant-containing polyolefin, and contacting the coated extrudate with a silane condensation catalyst and water. CONSTITUTION:A polyolefin (e.g., polyethylene) is fed from a hopper 2 into an extruder 1 and a solution prepared by dissolving a radical-generating agent (e.g., benzoyl peroxide) in a silane compound (e.g., vinyltriethoxysilane) is poured into the extruder 1 and reacted by heating. The reaction product is extruded alone or extrusion-coated around a conductor 7. At the same time, a colorant-containing polyolefin fed from the crosshead portion 6 of the extruder by a sub-extruder 5 is applied to the surface of the extrudate 8. The extrudate 8 is contacted with a siloxane condensation catalyst (e.g., dibutyltin dilaurate) and water to crosslink the polyolefin.
