Abstract: A method for purifying a polyoxyalkylene alcohol, which comprises treating with a treating agent consisting essentially of a pH buffer, a polyoxyalkylene alcohol containing a double metal cyanide complex catalyst, synthesized by ring-opening polymerization of an alkylene oxide in the presence of said catalyst, and then removing the catalyst and the treating agent from the polyoxyalkylene alcohol.

Abstract: A process for producing a shaped article of a non-cellular or microcellular polyurethane elastomer by reaction injection molding by using a high molecular weight active hydrogen compound component (A), a chain extender component (B) and a polyisocyanate compound component (C) as starting materials,wherein(I) the high molecular weight active hydrogen compound component (A) comprises(1) at least one polyoxyalkylene polyol (a-1) having an average molecular weight per hydroxyl group of from 800 to 4000 and an average number of hydroxyl groups per molecule of from 2 to 8 and containing at least 5% by weight of oxyethylene groups at the terminal portions of its molecules,(2) a high molecular weight amine (a-2) having from 2 to 8 active hydrogen-containing groups, and optionally(3) a high molecular weight polyol (a-3) other than the polyalkylene polyol (a-1), and(II) the chain extender component (B) comprises(1) a low molecular weight polyol (b-1) having from 2 to 4 hydroxyl groups and a molecular weight of at most
