Abstract

An insulation material comprising a substantially closed-cell polyurethane foam having the vapour of a fluorohalogenated hydrocarbon in the cells thereof, the polyurethane being derived from (i) a polyamide ester which has an acid number of less than 2, an amine number of less than 2, and a hydroxyl number not less than 400, and (ii) an organic polyisocyanate. The polyamide ester is preferably used in a proportion of 0.95 to 1.05 parts by weight, and the polyisocyanate is used in a proportion of 1.05 to 0.95 parts by weight, wherein the polyamide ester is the reaction product of (1) 1 to 1.4 mols. of a dicarboxylic acid, a dicarboxylic ester, a dicarboxylic acid chloride and/or a dicarboxylic anhydride; (2) 1.3 to 1.6 mols of a triol; and (3) 0.3 to 0.8 mols of an alcohol amine. The fluorohalogenated hydrocarbon preferably has a boiling point between 0 DEG C. and 60 DEG C., and is present in a proportion of 6 to 12% by weight of the polyurethane. Fluorohalogenated hydrocarbons mentioned are trichloromonofluoromethane, dichlorodifluoromethane, trichlorotrifluoromethane, dichlorotetrafluoroethane, dibromo difluoromethane, and mixtures of these. Dicarboxylic components of the polyamide ester mentioned are, dimethyl adipate, diethyl sebacate, diethyl succinate, adipic acid, dimethyl terephthalate, dimethyl isophthalate, dimethyl phthalate, succinic acid, terephthalic acid or isophthalic acid, and acid chlorides and anhydrides of these acids. Amine components mentioned are ethyleneamine, hexamethylene diamine and phenylene diamine; 3-amino-1, 2, propanediol, 2-amino-1, 3-propanediol, 3-amino-1, 4-hydroxymethyl benzene, N-2-hydroxyethyl, ethanolamine, 2, 3-diamino propane, hydroxymethyl paraphenylene diamine, N-hydroxy-ethyl-ethylene diamine, triaminomethyl propane, 1, 2, 3-triamino propane, and ethanol amine, 1-amino -2- propanol and 3 amino propanol. The triol component is trimethylolpropane. Polyisocyanates mentioned are toluene diisocyanate, diphenylmethane 4, 41 diisocyanate, toluene-2, 4-diisocyanate, toluene-2, 6 diisocyanate and mixtures thereof; 3, 31-bipolylene-4, 41-diisocyanate; 3, 31-dimethyl-diphenylmethane-4, 41-diisocyanate; hexylene 1, 6 diisocyanate; and m-phenylene diisocyanate. In Example 1, 30 gms of a polyamide ester, obtained from 1.2 mols of dimethyl adipate, 0.6 mol of ethanolamine, 1.45 mols of trimethyl propane and 0.06% by weight of lead monoxide, having a hydroxyl number of 420 and an amine number of 1.5, was mixed with 120 grams of toluene diisocyanate and 0.02 gram of phosphorus trichloride for 1 1/2 hours at 72 DEG C. in a nitrogen atmosphere to give an intermediate polymer. 100 grams of this polymer was mixed with 21 grams of trichloromono-fluoromethane and added to 60 grams of polyamide ester and 9.4 grams of ethylene glycol, in a mould. Foaming took place to give a polyurethane foam having a vapour of trichloromono-fluoromethane in the substantially closed-cells thereof.
