Copolyether polyol, polyurethane and method for producing copolyether polyol

摘要

The present invention relates to a copolyether polyol containing a monomer unit derived from tetrahydrofuran and a monomer unit derived from alkyltetrahydrofuran, having a terminal hydroxyl group purity of 97.0 to 100.0% and a molecular weight distribution (Mw / Mn). ) Is 1.05 to 2.5, and relates to a copolyether polyol, a polyurethane containing a unit derived from the copolyether polyol, and a method for producing the copolyether polyol.
