Abstract:
The present invention has its object to produce a highly reactive crystalline polyoxyalkylene polyol with a very high isotacticity at low cost, and provide polyurethane resins, and polyester resins which are excellent in sharp meltability. The present invention relates to a method for producing a crystalline polyoxyalkylene polyol having a number average molecular weight of 500 to 20,000 including performing ring-opening polymerization of an alkylene oxide (a) in the presence of a salen complex (B), the crystalline polyoxyalkylene polyol (A), and a polyurethane resin and a polyester resin produced by the crystalline polyoxyalkylene polyol (A).
