PROCESS FOR THE PREPARTIAON OF FLEXIBLE POLYURETHANE FOAMS INVOLVING THE USE OF AROMATIC MONOAMINES Abstract of the Disclosure The invention relates a process for the prepara- tion of a polyurethane foam by reacting an organic polyiso- cyanate, polyol, and primary or secondary aromatic monoamine in the presence of a blowing agent and catalyst. The amines are used in quantities of 0.1 part to 4 parts by weight per 100 parts per weight of polyol. The highly elastic polyurethane flexible foams are suited for the manufacture of upholstered furniture, matresses, automobile seats and head supports, as well as particularly for molded foams. The semi-rigid polyurethane foams are used as foam backing of dashboards in automobiles, thermal and sound insulation in buildings and vehicles, and for impact absorption in packaging materials.
