POLYOL, METHOD FOR PRODUCING THE SAME, POLYURETHANE RESIN OR POLYURETHANE FOAM OBTAINED FROM THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polyurethane resin or polyurethane foam having biodegradability and excellent mechanical properties and environmentally safe when released into the natural environment compared to the conventional technology, and to provide a polyol as a raw material for the resin or foam, easy to handle. SOLUTION: The polyol is obtained by carrying out a ring opening polymerization of at least one compound selected from the group consisting of lactides, lactams and lactones in the presence of an alkylglucoside.
