Abstract

In the production of foamed bodies by reacting with a polyisocyanate in the presence of water and a basic reaction accelerator, a polymer containing hydroxy and/or carboxylic acid groups, the reaction is conducted in the presence also of a non-basic metal compound, resulting in foams free from cracks and having a closed pore structure. Metal compounds specified are lead phenolate, iron and nickel carbonyls, ferric and zinc acetyl acetonates, ferric acetoacetate, iron, zinc, nickel and cobalt cyclopentanone carboxylic acid alkyl esters and ferric chloride. In a modification the polymer and polyisocyanate are reacted in the presence of the metal compound and the product reacted with water in the presence of the accelerator. Specified polymers are polyesters, polyesteramides, polyglycol ethers and polymers obtained by the polymerization of olefines and carbon monoxide with subsequent hydrogenation of the primary product. In examples (1) a polyester from adipic acid, diethylene glycol and trimethylol propane is mixed with 0.1 per cent of ferric acetyl acetonate at 80 DEG C. 200 parts of the mixture are reacted with stirring with 25 parts tolylene di-isocyanate and 7 parts of a mixture of 3 parts adipic acid ester of N-diethylethanolamine, 2 parts diethylamine oleate and 1.2 parts water. An elastic foam is produced. (1) 1 per cent of iron cyclopentanone carboxylic acid ethyl ester is mixed at 80 DEG C. with a polyester from adipic acid diethylene glycol and trimethylol propane and 100 parts of the mixture mixed with 31 parts of tolylene di-isocyanate at 80 DEG C. and left for 5 minutes. Ten parts of the water-accelerator mixture of Example 1 are added. A foam having a density of 50 kg/cm2. is obtained. A similar foam made without the iron compound contains cracks. The Specification gives long lists of polybasic acids and polyhydric alcohols from which the polyesters may be obtained, and refers to hexahydrodimethylaniline as an accelerator. Specification 769,680 is referred to.
