Abstract
There is provided a polyoxyalkylene polyol or monool (S) represented by formula (2). In the formula (2), R2 represents an m-valent group in which m active hydrogens are removed from the active hydrogen-containing compound (H); Z is an alkylene group or a cycloalkylene group, and these groups are unsubstituted or substituted with a halogen atom or an aryl group. A hydroxyl value x, total degree of unsaturation y and the content of ethylene oxide z satisfy mathematical expression (3). In mathematical expression (3), x represents 5 to 280 mgKOH/g, y represents total degree of unsaturation represented by a unit meq/g, and z is from 0 to 50.R2—[—(ZO)p-(AO)q-(CH2CH2O)r-H] (2)y≦18.9×x−2×(100−z)/100 (3)
