Preparation of noncellular polyurethane compositions

A process for preparing a noncellular polyurethane which comprises reacting an organic polyisocyanate with a chlorine-containing polyol in the presence of a catalytic amount of a metal carboxylate compound selected from the group consisting of an alkali metal salt of a carboxylic acid, an alkaline earth metal salt of a carboxylic acid and mixtures thereof, said chlorine-containing polyol having an average of 2-8 hydroxy groups and being comprised of the product of the acid-catalyzed condensation of a polyhydroxy initiator with 4,4,4-trichloro-1,2-epoxybutane or a mixture thereof with a halogen-free epoxide.
