Abstract

The instant invention is directed to a process for the production of molded foams having a compact surface and cellular core and an integral density distribution over the cross-section of the body, comprising reacting (A) polyisocyanates, and (B) relatively high molecular and/or low molecular compounds having an average of at least two isocyanate-reactive hydrogen atoms in the presence of: (C) catalysts for the isocyanate polyaddition reaction and (D) blowing agents and optionally other known additives, in a closed mold under the conditions of foaming inside molds, the improvement wherein said polyisocyanates are aliphatic and/or alicyclic polyisocyanates and said catalysts are catalyst combinations of: (i) an alkali metal and/or alkaline earth metal hydroxide and (ii) a metal compound, the metal compound being the acetylacetonate of iron, C1-C8 alcoholates, phenolates, enolates and/or acetylacetonates of metals of the 4th Main Group or sulfur compounds of metals of the 4th Main Group of the Periodic System of Elements in which the sulfur is directly attached to the metal atom.
