Abstract

PURPOSE:To improve stability to alcoholic hydroxyl groups of a hydrogen- containing flon useful as a foaming agent, aerosol agent or solvent, etc., by using styrene or derivative thereof. CONSTITUTION:A compound expressed by the formula (R<1>-R<4> are H or 1-3C hydrocarbon group) in an amount of 0.001-5.0wt.% preferably 0.05-2.0wt.% based on a hydrogen-containing flon (lower aliphatic halogenated hydrocarbon containing F, halogens other than the F and at least one H) is contained therein to stabilize the hydrogen-containing flon against alcoholic hydroxyl groups. Storage stability of a polyol containing the hydrogen-containing flon as a foaming agent is especially improved. In forming a polyurethane foam, decomposition of the hydrogen-containing flon, premixed with polyols and stored for a long period in storage can be suppressed according to this method without adversely affecting the formation of the above-mentioned foam.
