PURPOSE:To obtain the title molded product which is useful as a water pump blade or the like, because its stiffness is improved and the crosslinking time is shortened, by forming a molded product from a specific polyolefin and crosslinking the product by bringing into contact with a polyol solution. CONSTITUTION:A polyolefin which is prepared by copolymerizing an ethylenically unsaturated silane compound bearing a hydrolyzable organic group is molded, and the product is brought into contact with a polyol solution containing a difunctional or more functional polyol such as ethylene glycol to give the subject molded product. Said silane compound is, for example, a compound of the formula (R is an ethylenically unsaturated hydrocarbon; R is aliphatic saturated hydrocarbon; Y is a hydrolyzable organic group; n is 0, 1, 2), preferably vinyl trimethoxysilane. |
