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.
