    摘要: A (meth)acrylate-grafted polyether polyol produced by reacting 40 to 95 parts by weight of a polyoxyalkylene polyol and 5 to 60 parts by weight of a vinyl monomer, both relative to 100 parts by weight of the sum total of the polyoxyalkylene polyol and the vinyl monomer, and 0.1 to 5 moles of an alkyl peroxide as a radical initiator per mole of the hydroxyl group in the polyoxyalkylene polyol, wherein the polyoxyalkylene polyol has a hydroxyl number of 25 mg KOH/g or less, and the vinyl monomer contains a (meth)acrylate and/or a hydroxyl-containing (meth)acrylate in an amount of 50% by weight or higher. The (meth)acrylate-grafted polyether polyol is excellent in colorless-transparency, compatibility, mechanical strength, weather resistance, and blending resistance, and therefore is useful as a raw material for a polyurethane resin cured article.
