The crystalline polyhydroxy compound is insoluble or only slightly soluble in the polyol to be foamed and melts within the temperature range of about 60.degree.-160.degree. C. The amount of crystalline polyhydroxy compound to be used corresponds to about 0.1-5.0 hydroxy equivalent weights per 1 hydroxy equivalent weight of the polyol to be foamed.
