    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.

    摘要： The present invention is aimed at providing a toner binder for electrophotography that is excellent in the fixing property, offset resistance, blocking property, grindability, durable developing property and the like to correspond to the high-speed movement of a copier. The purpose of the present invention could be achieved by a toner binder having the following features for electrophotography. That is, when the viscoelasticity of the toner binder is measured in the temperature range of 50 to 200 ° C. and at a heating rate of 2° C./min., the viscoelasticity curve in the temperature range of 100 to 200° C. showing the relationship between the storage modulus and temperature, in which curve the axis of ordinate is the logarithm (Pa) of storage modulus G′ and the axis of abscissa is temperature (° C.), has a concave in the temperature range of 140 to 180° C. and has a minimum value of storage modulus G′ at the bottom of the range, and this G′ 0 and storage modulus G′ 200 at 200° C. are G′ 0
