Abstract
A polymer polyol (I) is provided that is formed of a polyol (A), polymer particles (B) obtained by polymerization of an ethylenically unsaturated compound (b), and an active-hydrogen-containing compound (d) having an aromatic ring and having a number-average molecular weight of 150 to 2,000, wherein a content of (d) is 1 to 20% on the basis of a weight of (B). The polymer polyol of the present invention contains polymer particles having sufficiently small particle diameters, has a low viscosity, and has excellent handleability. A polyurethane resin obtained by using the polymer polyol of the present invention has excellent mechanical strengths such as elongation at break.
