    Abstract: Storage-stable emulsion, used in the manufacture of fine celled hard foamed materials, contains a polyester alcohol propellant of specified formula as emulsifier. Emulsion contains: (a) compounds containing hydrogen atoms reactive towards isocyanates; (b) a polyester alcohol propellant of formula (I) as emulsifier; and (c) usual polyurethane catalysts, auxiliary aids and/or additives. (b) is emulsified in components (b) and (c). m = 0-15; n = 0-1; o = 0-15; p = 0-1; q = 0-15; r = 0-1; s = 0-15; t = 0-1; u = 0-10; v = 0-15; x = 1-5; y = 1-4 or mixtures between 1-3 with r + n is not 0; R1 = aliphatic structure based on the structure of multivalent alcohols, preferably ethylene glycol, diethylene glycol, triethylene glycol 1,2-propylene glycol, and dipropylene glycol; 1,4-butane diol, 1,6-hexane diol, neopentyl glycol, 1,3-butane diol, trimethylol propane, trimethylol ethane, glycerin, pentaerythrite; R2 = polycarboxylic acid without COOH groups, e.g. adipic acid, terephthalic acid, or o-phthalic acid; and R3 = alcohol as in R1.
