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: 4,4'-disubstituted bis-(2,6-diisopropylphenyl)carbodiimides of the formula (I) (see fig. I) where R is 1-methyl-1-phenylethyl, phenoxy or tert-butyl, a process for their preparation, their use as stabilizers against hydrolytic degradation of polyaddition and polycondensation products containing ester groups, and the novel 4-(1-methyl-1-phenylethyl)-2,6-diisopropyl-, 4-phenoxy-2,6-diisopropyl- and 4-tert-butyl-2,6-diisopropylphenyl isocyanates which can be used for their preparation.

Abstract: The subjects of the invention are novel carbodiimides and/or oligomeric polycarbodiimides having terminal isocyanate, urethane and/or urea groups, obtainable e.g. by condensation with elimination of carbon dioxide of 1,3-bis(1-methyl-1-isocyanatoethyl)benzene and thereafter optionally partial or complete reaction of the free isocyanate groups of the resulting (poly)carbodiimides with aliphatic, cycloaliphatic or araliphatic amines, alcohols and/or alkoxypolyoxyalkylene alcohols, a process for their preparation and their use as a stabiliser against the hydrolytic degradation of polyaddition and polycondensation products containing ester groups.
