Blowing agent-containing emulsions comprise a) compounds containing hydrogen atoms which are reactive toward isocyanates, b) blowing agents, c) catalysts, auxiliaries and/or additives which are customary in polyurethane chemistry, wherein the blowing agents b) are present as an emulsion in the components a) and c), and polyester alcohols having the following structure are used as emulsification aids: Image where 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 of 1-3 where r + n ~ 0 z = 0 - 3 Z i = 0.1 - 3 R1 is an aliphatic structure without OH groups, based on the structure of polyhydric alcohols, preferably ethylene glycol, diethylene glycol, triethylene glycol, 1,2-propylene glycol and dipropylene glycol, 1,4-butanediol, 1,6-hexanediol, neopentyl glycol, 1,3-butanediol, trimethylolpropane, trimethylol ethane, glycerol, pentaerythritol, where these substances can also be used as any mixture with one another in the esterification and R1 can therefore also be a mixture of the corresponding structures, R2 is the radical of a polycarboxylic acid without COOH groups, eg. adipic acid, terephthalic acid, o-phthalic acid, R3 is an alcohol radical like R1.

Divulgation d'émulsions contenant des agents d'expansion, comprenant : a) des composés renfermant des atomes d'hydrogène capables de réagir avec les isocyanates, b) des agents d'expansion et c) des catalyseurs, des auxiliaires et/ou des additifs habituellement utilisés en chimie des polyuréthanes. Dans ces compositions, les agents d'expansion b) se retrouvent sous forme d'émulsion dans les composés a) et c), et on utilise comme agent d'émulsification des polyesters-alcools ayant la structure suivante, Image , dans laquelle : 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 ou des mélanges dans lesquels y = 1-3 et r + n 0; z1 = 0-3, z2 = 0-3 et z1 + z2 = 1-3; et R1 est une structure aliphatique ne portant aucun groupement OH, provenant d'une structure de polyalcool, de préférence une structure d'éthylèneglycol, de diéthylèneglycol, de triéthylèneglycol, de 1,2-propylèneglycol, de dipropylèneglycol, de 1,4-butanediol, de 1,6-hexanediol, de néopentylglycol, de 1,3-butanediol, de triméthylolpropane, de triméthyloléthane, de glycérol, de pentaérythritol ou d'une combinaison de ces structures, obtenue par estérification de n'importe quel mélange de ces substances; R2 est le radical correspondant à un acide polycarboxylique sans groupement COOH, comme p. ex., l'acide adipique, l'acide téréphtalique ou l'acide orthophtalique; et R3 est un radical d'alcool du type de R1.
