Abstract

A process for the manufacture of cellular polyurethanes from polyisocyanates, hydroxyl group-containing polymers such as polyesters, polyethers or polyesteramides and, as desired, water and other agents, is characterized in that as a catalyst there is used at least one tertiary amine salt of an acid ester of phosphoric acid. Specified tertiary amines are triethylamine, N:N-dimethyl cyclohexylamine, N-methyl morpholine, 2-(21-diethylaminoethyoxy)-propionitrile, trinonylamine, N1N1N11N1-tetraethylhexamethylene diamine, N-(3-diethylaminopropyl) succinimide, N1N-dimethylbenzylamine, 2-diethylaminoethyl carbanilate, b -diethyl aminoethyl alcohol, triethanolamine and N-ethylpiperidine. Preferred acid esters are mono- and dialkyl esters of phosphonic acid wherein the alkyl groups are ethyl, propyl, butyl, amyl, benzyl, lauryl, palmityl and stearyl. In a typical Example (5) a foam is prepared by mixing a liquid polyester from castor oil and citric acid; an oleyl/octyl alcohol reaction product with ethylene oxide; water; tri-b -chloroethyl phosphate; and the neutral salt of N:N-dimethylbenzylamine with a mixture of mono- and di-n-butyl orthophosphates, and adding to the mixture a diisocyanate composition obtained by phosgenating crude diaminodiphenylmethane resulting from the condensation of formaldehyde with aniline. Specifications 839,185 and 879,167 are referred to.ALSO:A process for the manufacture of cellular polyurethanes from polyisocyanates, hydroxyl group-containing polymers such as polyesters, polyethers or polyesteramides and, as desired, water or other agents, is characterized in that as a catalyst there is used at least one tertiary amine salt of an acid ester of phosphoric acid.
