Abstract

PURPOSE: To improve the stability of flon (a halogenated lower aliphatic hydrocarbon containing fluorine and halogen other than fluorine) to alcoholic group, by using a styrene compound and a monohydric phenol as stabilizers.
CONSTITUTION: Flon is stabilized to alcoholic hydroxyl group by incorporating a system containing flon and alcoholic hydroxyl group with (A) a compound of formula (R1WR3 are H or 1W3C hydrocarbon group), e.g. α-methylstyrene, and (B) a monohydric phenol such as 2,6-di-t-butyl-p-cresol. The amounts of the components (A) and (B) are pref. 0.05W2.0% and 0.001W0.5%, respectively. The process is useful for improving the storage stability of polyol containing flon as a foaming agent of polyurethane.
