Abstract

PURPOSE: To obtain a corsslinked polyolefin for insulated wires having steady appearance, by extruding and moding pellets impregnated with a silane, a radical initiator, siloxane condensation catalyst, and a polyhydric phenol.
CONSTITUTION: Pellets of a polyolefin, e.g. low-density polyethylene, etc. are impregnated with a liquid, wherein (A) a silane, e.g. vinyltrimethoxysilane, etc., (B) a radical initiator, e.g. dicumyl peroxide, etc., (C) an antioxidant, e.g. poly- 2,2,4--trimethyl-1,2-dihydroquinoline, etc., (D) a siloxane condensation catalyst, e.g. dibutyltin dilaurate, etc., and (E) a phenol, e.g. 4,4'-isopropylidenebisphenol, etc. having a molecular weight ≤ 400, and two or more hydroxyl groups are dissolved, at 60W80°C with agitation. The pellets thus obtained are molded by an extruder under heating into an article, which is brought into contact with water and crosslinked.
