Summary:PROBLEM TO BE SOLVED: To provide a polyurethane resin which is excellent in durability such as heat resistance while securing preferable mechanical property and flexibility, and to provide an acrylic-modified polyol which can be suitably used as a starting material of the polyurethane resin. SOLUTION: The acrylic-modified polyol is produced by reacting (meth)acrylic ester with at least one kind of macropolyol selected from polyester polyol, polycaprolactone polyol and polycarbonate polyol in the presence of a radical reaction initiator of 0.55 mol% or less per 1 mol of hydroxy group in the macropolyol. The polyurethane resin is obtained by reacting the acrylic-modified polyol thus produced, polyisocyanate and a chain extender. COPYRIGHT: (C)2011,JPO&INPIT
