Abstract: The invention concerns a process for the manufacture of flame resistant flexible polyurethane foams by reacting a mixture of diphenylmethane diisocyanates and polyphenylene polymethylene polyisocyanates having a functionality greater than 2 containing 40 to 90 percent by weight diphenylmethane diisocyanate based on the total weight of said mixture; polyols, cyanic acid derivatives such as cyanamide, dicyandiamide, guanidine, biguanidine, melamine, cyanuric alkyl esterhydrazides and -amides as flame inhibitors, and blowing agents; as well as, possibly, chain extenders and other additives. The flexible polyurethane foams are suited for the familiar areas of applications, but especially as sound-insulation material for the construction industry.

Abstract: Use is claimed of 24-34C fatty acids (and/or their amides and/or esters) in the production of polyisocyanate-polyaddition products with reduced tendency to absorb and/or desorb substances, the production comprising reacting (a) a polyisocyanate with (b) an NCO-reactive compound of mol. wt. 500-8,000, (c) optionally also a chain extender and/or crosslinker of mol. wt. below 500, (d) a catalyst and (e) conventional additives etc in presence of the fatty acid and/or derivative.
