Abstract

The invention concerns a method for inhibiting the reaction between hydrochlorofluorocarbons and organic substances containing atoms of reactive hydrogen in the uses in which the aforesaid hydrochlorofluorocarbons come into contact with these substances, in particular in polyol-based formulations for the preparation of expanded polyurethanes. According to the invention, small quantities of a stabilizing substance selected from particular polyalkenes containing at least one pair of conjugated ethylenic double bonds or particular mononitroalkanes are used.
