Abstract

PURPOSE: To obtain a molded article of the title copolymer composition having uniformed characteristics, by adding a silanol condensation catalyst to the powdered ethylene-propylene copolymer subjected to silane graft reaction to form the molded article, which is treated by water.
CONSTITUTION: A silane compound shown by the formula RR'SiY2 (R is monofunctional olefinic unsaturated hydrocarbon, group etc.; Y is hydrolyzable organic group; R' is monofunctional hydrocarbon group having no aliphatic unsaturated bond) is grafted onto an ethylene-propylene copolymer resin, obtained by grinding bale ethylene-propylene copolymer by a grinder, at not lower than 140°C in the presence of a compound capable of producing free radical parts in the copolymer to give a silane grafted ethylene-propylene copolymer resin, which is molded in the presence of a silanol condensation catalyst to make a molded article. The molded article is treated by water to undergo silane crosslinking.
