Abstract

In an improvement or modification of the process of the parent Specification a fatty acid ester containing at least two hydroxyl groups in the molecule is incorporated into or mixed with the polyhydroxy compound specified in the parent Specification. The ester may be mixed with the polyhydroxy compound or may be incorporated into the polyhydroxy compound during its manufacture by inclusion with the reactants used to form the polyhydroxy compound. Alternatively the ester and the polyhydroxy compound may be linked by reaction with a diisocyanate to give a material still containing OH groups, which is then reacted with polyisocyanate. Specified fatty acid esters are castor oil, hydrogenated castor oil, ricinoleic glycol esters, ricinoleic - 5,18 - octadecenediol monoesters, reaction products of castor oil, oleic acid, phthalic acid and glycol, monoglycerides of oleic, stearic, and palmitic acids, the OH groups of which have been reacted with ethylene oxide, and hydroxyethylated monoesters of oleic, stearic and palmitic acids with trimethylol propane or pentaerythritol. In a typical example, (1) a hydroxy compound obtained by condensing 1,4-butane-b -dihydroxyethyl ether, castor oil and paraformaldehyde in the presence of p-toluene sulphonic acid is reacted with toluylene diisocyanate and water in the presence of ethyl g -dimethylaminopropyl ether, diethyl ammonium oleate and aqueous sulphonated castor oil, to give a foam.ALSO:In an improvement or modification of the process of the parent Specification a fatty acid ester containing at least two hydroxyl groups in the molecule is incorporated into or mixed with the polyhydroxy compound specified in the parent Specification.
