<P>PROBLEM TO BE SOLVED: To provide a urethane resin which has a high molecular weight and is excellent in tensile strength. <P>SOLUTION: The urethane resin is obtained by reacting a polyoxypropylene glycol (A) having a weight-average molecular weight of 100,000-2000,000 with a diisocyanate (B). The urethane resin composition uses the urethane resin. <P>COPYRIGHT: (C)2010,JPO&INPIT |
