Abstract

Foamed polyurethane materials are manufactured by the interaction of an organic polyisocyanate with a hydroxyl group containing polymer in the presence of a halogen-substituted hydrocarbon of low boiling point by a process which comprises the steps of incorporating a gaseous halogen-substituted hydrocarbon having a boiling point between - 50 DEG C. and 50 DEG C. at atmospheric pressure in a hydroxyl group containing polyester, polyesteramide or polyether and then reacting the hydroxyl group containing polyester, polyesteramide or polyether with an organic polyisocyanate optionally in the presence of water. Particularly suitable halogen substituted hydrocarbons are those which contain at least one fluorine atom per molecule, particularly monofluorotrichloromethane. In the examples there are utilized polyethers prepared by the reaction of propylene oxide with triethanolamine, sorbitol or trimethylolpropane. The reaction mixture may also include catalysts, particularly tertiary amines and organic compounds of metals, surface-active agents such as oxethylated phenols and fatty alcohols, block copolymers of ethylene and propylene oxides, silcone fluids and particularly siloxano-oxyalkene block copolymers and other additives such as cross-linking agents, foam-stabilizing agents, colouring matters, fillers, plasticizers, flame retardents and antioxidants.
