Abstract: Organic materials which contain from 0.001 to 10% by weight of an aminoreductone I I where R1, R2 and R3 are H, methyl or ethyl and R4 is the radical of a naturally occurring .alpha.- or .beta.-aminoacid or of a C1-C10-alkyl ester thereof or, in the case of an .alpha.aminoacid, a lactone having a 2-OH group in the cyclohexenone ring, or R4 is C1-C20-alkyl which is unsubstituted or substituted by -OH, C1-C4-alkoxy or C1-C4-acyloxy, or is -(CH2-CH2-O)nH, which may be etherified with a C1-C4-alkanol or esterified with a C1-C4-fatty acid, and where n is from 2 to 10, or a mineral salt thereof. Novel compounds Ia differ from I in having the radical R4a, where R4a is R4 with the exception of methyl. Compounds I are prepared by reacting the corresponding 2,3-dihydroxycyclohex-2-en-1-one with an amine HN(R3)R4 or a mineral acid salt thereof. 25.

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.
