Abstract: The invention relates to novel 4,4'-disubstituted bis(2,6-diisopropylphenyl)carbodiimides of the formula (I) in which R is a 1-methyl-1-phenylethyl, phenoxy or tert-butyl radical, to a process for their preparation and to their use as stabilisers with respect to the hydrolytic degradation of ester group-containing products of addition and condensation polymerisation, and to the novel compounds which can be used to prepare them, namely 4-(1-methyl-1-phenylethyl)-2,6-diisopropylphenyl, 4-phenoxy-2,6-diisopropylphenyl and 4-tert-butyl-2,6-diisopropylphenyl isocyanates.

Abstract: PROCESS FOR THE PREPARATION OF FLAME RESISTANT ELASTIC POLYURETHANE FLEXIBLE FOAMS AND LOW VISCOSITY MELAMINE POLYETHER POLYOL DISPERSIONS THEREFOR The present invention deals with a process for the preparation of flame resistant, elastic polyurethane flexible foams, comprising reacting: a) organic and/or modified organic polyisocyanate; with b) higher molecular weight polyols; and c) 1,6-hexanediol and/or trimethylolpropane; in the presence of d) melamine or mixtures of melamine and other flame retardants; e) at least one blowing agent; and f) at least one catalyst; and optionally g) auxiliaries and/or additives. In addition the present invention deals with suitable low viscosity melamine and polyetherpolyol dispersions for the process of the present invention comprising melamine, 1,6hexanediol and/or trimethylolpropane and at least one polyetherpolyol.
