Abstract: The invention relates to novel esters which contain fluorocarbon and oxypropylenealkyl ether groups in bonded form, of the formulae in which: Rf is a linear or branched, partially fluorinated or perfluorinated alkyl group having 2 to 10 carbon atoms, a partially fluorinated or perfluorinated cycloalkyl group having 4 to 8 carbon atoms, a perfluorophenyl group or a perfluoroalkylphenyl group having 1 to 6 carbon atoms in the perfluoroalkyl radical, R is a linear or branched alkyl group having 1 to 4 carbon atoms and n is an integer from 2 to 70, to storage-stable, blowing agent-containing emulsions which contain at least one partially fluorinated or perfluorinated (cyclo)aliphatic hydrocarbon having 3 to 8 C atoms and/or sulphur hexafluoride, at least one optionally modified organic polyisocyanate or a higher-molecular-weight reactive hydrogen compound and at least one of the abovementioned carboxylates or carbamidates, and to the use of these emulsions for the preparation of cellular plastics by the polyisocyanate polyaddition process.
