Abstract
Polyurethane foam is prepared by reacting an alkylene diphenylene diisocyanate with a polyol which is a mixture of a polytriol with a M.W. of 2400 to 6000 and a minor amount of a trihydric alcohol of equivalent weight less than 100, in the presence of a polymerization catalyst and a blowing agent. The alkylene diphenylene diisocyanates may be unsubstituted or substituted with groups such as alkyl, alkoxy or halogen. Suitable polytriols are those prepared by reacting an alkylene oxide with triols such as glycerol, 1,2,6 - hexanetriol, trimethylolpropane, 1,2,4 - butanetriol and trimethylolethane. The trihydric alcohol used as a minor component of the mixture may be one of those triols mentioned above and in addition triethanolamine, tripropanolamine, triisopropanolamine, tributanolamine and 1,3,4 - trimethylolbutane. Preferred catalysts are tertiary amines and organotin compounds and mixtures thereof. The blowing agents may be water and fluorine containing hydrocarbons. Conventional foam stabilizers may also be used.
