    摘要： An object of the present invention is to provide a polyoxyalkylene polyol and a polyoxyalkylene monool, capable of producing a urethane elastomer and a urethane foam which are sufficiently excellent in mechanical properties and moisture resistance.
    The present invention is directed to a polyoxyalkylene polyol or monool (S), which is an alkylene oxide adduct of an active hydrogen-containing compound (H), wherein 40% or more of hydroxyl groups located at the terminal are primary hydroxyl group-containing groups represented by the general formula (1) shown below, and a hydroxyl value x, the total degree of unsaturation y and the content of ethylene oxide z satisfy a relationship of the mathematical expression (1).

    [In the general formula (1), R 1 represents a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, a cycloalkyl group or a phenyl group, each of which may be substituted with a halogen atom or an aryl group.] y ≤ 28.3 × x - 2 × 100 - z / 100
    [In the mathematical expression (1), x represents a hydroxyl value, y represents the total degree of unsaturation, and z is the content of ethylene oxide based on the weight of (S) and is from 0 to 50% by weight.
