Abstract

PURPOSE: To readily crosslink a silane-grafted polyolefin resin within a short time, by carrying out the reaction in the presence of a silanol condensation catalyst by using a water-containing high-boiling liquid material at 100°C or higher.
CONSTITUTION: A high-boiling liquid material having mutual solubility in water and a b.p. ≥100°C (a higher alcohol such as n-butyl alcohol or ethylene glycol is preferred) is employed by combining the liquid with an appropriate amount of water. That is, a silanol condensation catalyst is added to a silane-grafted polyolefin and the mixture is molded. The molding is crosslinked by immersing it in said water-containing high-boiling liquid material heated to 100°C or higher. Here, if the silanol condensation catalyst is added also to said water-containing high- boiling liquid material, the time required for crosslinking treatment can be shortened further.
