摘要： The present invention provides a process comprising reacting polyisocyanate with active hydrogen-containing compound in the presence of Z-1,1,1,4,4,4-hexafluoro-2-butene at a temperature of at least 135° F. (57.2° C.) or a temperature of 135° F. (57.2° C.) to 150° F. (65.6° C.) to obtain as a result thereof, foamed reaction product, wherein the thermal conductivity of the foamed reaction product exhibits no appreciable change at any of the foaming temperatures within this range.
