摘要： PURPOSE:To greatly reduce the deterioration of connected parts of shaped polyethylene pieces, by previously appropriately impregnating the connected parts with a prescribed silane compound and a compound which produces a free radical on polyethylene at a high temperature, melting the connected parts and butt-coupling them to each other. CONSTITUTION:The connected parts of the shaped polyethylene pieces such as pipes are previously appropriately impregnated with the silane compound such as vinyltrimethoxysilane which is represented by a general formula RR'SiY2 and with the compound such as dicumyl peroxide or BPO which produces the free radical on polyethylene at the temperature of 140 deg.C or more. The connected parts are heated to a temperature of 160 to 250 deg.C equal to the melting point of polyethylene and butt-coupled to each other. In said formula, R denotes a monovalent olefinic unsaturated hydrocarbon group or a hydrocarbon oxy group, Y denotes a hydrolyzable organic group and R' denotes hydrogen or a monovalent hydrocarbon group containing no fatty unsaturated part.
