Abstract

1,184,893. Foamed polymers containing isocyanate groups. IMPERIAL CHEMICAL INDUSTRIES Ltd. 11 April, 1967 [22 April, 1966], No.17730/66. Headings C3C and C3R. Foamed polymers containing an isocyanate ring structure are prepared by reacting in the presence of a blowing agent and a catalyst for the polymerization of isocyanates, a polyol of M.W. greater than 300 and a crude diisocyanatodiarylalkene composition containing 5 to 70% by weight of polyisocyanates of functionality greater than two, in such amounts so as to provide at least 1À7 equivalents of isocyanate group for each equivalent of active hydrogen. Preferred diisocyanatodiarylalkane compositions are the diisocyanatodiphenylmethane compositions which may be optionally halogenated. Conventional linear and branch chained polyethers or polyesters are preferably used. The blowing agent may be water and/or inert low boiling liquids especially halogenated hydrocarbons. Catalysts which may be used are strong bases, e.g. quaternary ammonium hydroxides, alkali metal hydroxides and alkoxides, alkali metal salts of carboxylic acids, certain tertiary amines and non-basic metal salts of carboxylic acids, e.g. lead octoate. Mixtures of the above catalysts with conventional catalysts, used in the formation of polyurethanes, may be used. The reaction mixture also may contain surface active agents, plasticizers, flame-retardants, fillers and antioxidants.
