POLYURETHANE MOLDING HAVING EXCELLENT RESISTANCE TO WATER ABSORPTION.

摘要

This invention relates to a polyurethane molding having a density of 0.5 to 1.2 g/cm<3>, containing tris( beta -chloropropyl)phosphate and being excellent in the resistance to water absorption. This molding is produced by the reaction of a polyisocyanate, a polyol and a cross-linking agent, if necessary in the presence of a catalyst, a flowing agent and other additives, in a mold, wherein tris( beta -chloropropyl)phosphate is added to the reaction mixture.
