摘要： A polybutadiene having a hydroxyl group at a terminal end thereof is reacted with a lactone compound such as an µ-caprolactone to obtain a polymer polyol represented by formula (I): HO-X 1 -Y-X 2 -OH (wherein X 1 and X 2 each independently represents a polyester component and Y represents a polybutadiene component), the polymer polyol is reacted with an unsymmetric diisocyanate to obtain a urethane prepolymer, and then the urethane prepolymer is reacted with a chain extender to obtain a polyurethane.

摘要： The present invention provides a polyol composition comprising a polyol having a polyester chain, wherein the polyol composition substantially contains no metal-base polymerization catalyst and an amount of phosphorus element derived from a polymerization catalyst is 1 to 1000 ppm. Furthermore, the present invention provides a method for producing a polyol composition comprising reacting a compound having an active hydrogen with a compound having at least one selected from the group consisting of carboxyl group, ester group and acid halide group in the presence of 0.0001-0.05 parts by mol of a phosphorus compound with respect to 1 part by mol of the active hydrogen without using a metal-based polymerization catalyst.
