Abstract
Abstract POLYURETHANE FOAMS HAVING IMPROVED PHYSICAL PROPERTIES ARE PROVIDED HEREIN BY PRODUCING THE FOAMS IN THE PRESENCE OF CELL MODIFYING AGENTS, AT LEAST ONE OF WHICH IS AN ORGANIC HIGH MOLECULAR WEIGHT EMULSIFYING AGENT SUBSTANTIALLY SOLUBE IN MINERAL OIL BUT SUBSTANTIALLY INSOLUBLE IN WATER, AND WHICH EMULSIFYING AGENT IS CAPABLE OF PRODUCING HEAT-STABLE WATER-IN-OIL EMULSIONS. THE EMULSIFYING PROPERTIEW OF THESE NEW CELL MODIFYING AGENTS ARE SUCH THAT UPON SUBJECTING 20 CM.3 OF 0.5% SOLUTION OF SAID EMULSIFYING AGENT IN A MINERAL OIL OF A VISCOSITY OF 1-5* ENGLER AT 20*C. TO THE A.S.T.M. "STEAM EMULSION TEST"; THE TIME FOR SEPARATING 5 CM.3 OF ONE OF THE PHASES OF THE EMULSION AT A TEMPERATURE OF 93*C. TO 95*C. IS AT LEAST 20 MINUTES.
