Abstract
PURPOSE: To prepare an ethylene copolymer with excellent crosslinking characteristics, by the high-pressure radical polymerization of ethylene with an ethylenically unsaturated silane compound in the presence of a radical polymerization initiator and an α-olefin.
CONSTITUTION: Ethylene and 0.001W0.2wt% ethylenically unsaturated silane compound of formula R'SiR2nY3-n [wherein R' is an ethylenically unsaturated hydrocarbon(oxy); R2 is an aliphatic saturated hydrocarbon; Y is a hydrolyzable organic group; n is 0W2] are subjected to high-pressure radical polymerization at a polymerization pressure of 500W4,000kg/cm2, at a maxinum reaction temperature of 240W350°C in the presence of a radical polymerization initiator (e.g., t-butyl peroxybenzoate) and, as a chain transfer agent, an α-olefin.
