Abstract

PURPOSE: To improve an impact resistance, an environmental stress crack resistance, and a heat resistance, by a method wherein powder of a crosslinked polyolefin, copolymerized with a specified unsaturated silane compound, is rotation-molded, and a molded product is brought into contact with water in the presence of a catalyst.
CONSTITUTION: After powder of a polyolefin, copolymerized with an ethylenically unsaturated silane compound containing a hydrolyzable organic group, is rotation- molded, the product is brought into contact with water in the presence of a silanol condensation catalyst for crosslinking. Vinyltrimethoxysilane, vinyltriacetoxysilane, etc. are suitable as an ethylenically unsaturated silane compound having a hydrolyzable organic group. Dibutyltin dilaurate, dibutyltin diacetate, etc. are used as a silanol condensation catalyst, and an addition amount is 0.001W10wt%, preferably 0.01W5wt%, on the basis of a molded product.
