Abstract
A prepolymer, comprising a hydroxyl-group containing resinous compound and a stoichiometric excess of an isocyanate compound which have been vigorously agitated and rapidly cooled to below the freezing point of the isocyanate compound, is mixed with a catalyst below the temperature at which gas is liberated, and is then discharged so that a foaming reaction occurs when the temperature is raised and a polyurethane foam is formed. The foaming mixture can be cast into thin cellular foam sheets by spreading the mixture on a carrier belt and allowing it to expand. In the example polyurethane foam is made from a mixture of 80% toluene 2,4-di-isocyanate and 20% toluene 2,6-di-isocyanate and a diethylene glycol-adipic acid polyester using an aqueous solution of N,N,N1,N1-tetra-methylbutane diamine and triethylene diamine as catalyst.
