ABSTRACT:
A method of manufacturing a modified polyhydroxy compound, which is characterized in that a polyhydroxy compound is heated for 30 minutes or more at a temperature ranging from 150.degree. to 250.degree. C. under stirring and in the presence of tin, tin compounds such as tin halogenide, tin hydroxide and tin oxide. The polyhydroxy compound modified by this method is effective in improving the foamability and mechanical strength of urethane foam, when it is used as a raw material in the manufacture of urethane foam.
