Abstract
A method of making a polyurethane foam comprises reacting a polyalkylene ether polyol and an organic polyisocyanate (or a prepolymer formed therefrom) in the presence of a foaming agent, a metal containing catalyst and a minor amount of polysiloxane-polyoxyalkylene block copolymer. Specified polyalkylene ether polyols are those derived by condensing one or more alkylene oxides with a polyhydric alcohol e.g. glycerol, hexanetriol-1:2:6 and pentaerythritol. Specified metal containing compounds are polymeric organo-tin compounds, dibutyl tin laurate, tin maleate, potassium stearate, zinc stearate, sodium stearate, potassium acetate, sodium acetate, sodium and potassium hydroxide and carbonate and sodium methyl siliconate. Specified polysiloxane-polyoxyalkylene block copolymers are those of the formula: <FORM:0944904/C3/1> where R1, R2 and R11 are monovalent hydrocarbon radicals, p, q, and r are integers, n is an integer from 2 to 4 and s is an integer of at least 5. Water is the specified foaming agent. Cross-linking agents e.g. trimethylol propane, glycerol, 1:2:4-butamediol, hexanetriol, pentaerythritol, the b -ethanol ether of 2-methyl-2-methylol-4-methyl-5-hydroxypropane, N:N:N1:N1-tetrakis(2-hydroxypropyl) ethylene diamine and hexamethylene diamine may be present in the reaction mixture as may tertiary amine catalysts, e.g. di(ethylene amino alcohol) adipate, dibutyl aminoethanol, butyl diethanolamine, triethylamine, trihexylamine, tributylamine, tripropylamine, N-methyl morpholine, N-octyl morpholine, 4-pyridine propanol and 4-n-amyl pyridine. In the examples, foamed polyurethanes are made by reacting a condensation product of propylene oxide and glycerol with toluylene diisocyanate in the presence of: <FORM:0944904/C3/2> (where (CnH2nO)w is a mixed polyoxyethylene-oxypropylene block containing n oxyethylene and 13 oxypropylene units), dimethyl cetyl t-amine, a mixture of mono- and di-phenyl-n-heptylamines and (1) aqueous sodium hydroxide; (2) aqueous sodium hydroxide, zinc stearate and starch and (3) zinc stearate and water. Specification 804,369 and U.S.A. Specification 2,834,748 are referred to.
