Abstract

PURPOSE:To obtain a molded article of polyolefin crosslinked by silane, wherein graft reaction is carried out smoothly, by kneading polyolefin, a silane compound, a free radical generator, a polyolefin having a high softening point containing a condensation catalyst at a high and a low temperatures by an extruder. CONSTITUTION:A polyolefin (P1) is kneaded with B) a silane compound shown by the formula PR'SiY2 (R is a monofunctional olefinic unsaturated hydrocarbon group or a hydrocarbonoxy group; Y is hydrolyzable organic group; R' is R, Y, or H), C) other polyolefin (P2) having a higher softening temperature than that of polyolefin (P1), blended with a silanol condensation catalyst, at a temperature between a softening point of P1 and that of P2 by an extruder and kneaded again at a temperature not lower than that of P2. A molded article obtained is crosslined by permitting it to stand in a moisture-containing atmosphere.
