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: 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.

Abstract: A process for the production of mouldings having a cellular core and a compacted peripheral zone and improved demoulding properties by the polyisocyanate polyaddition process, by reacting a) organic polyisocyanates b) relatively high-molecular-weight compounds containing at least 2 reactive hydrogen atoms, and, if desired, c) low-molecular-weight polyhydric alcohols, polyoxyalkylene-polyols and/or secondary aromatic diamines in the presence of d) an internal mould release agent, comprising A) from 0.1 to 12% by weight, based on the total weight of components (b) and (c), of a mixture of i) from 5 to 80 parts by weight of at least one organic amine, and ii) from 20 to 95 parts by weight of at least one metal salt of stearic acid, and B) from 0.01 to 32% by weight, based on the total weight of components (b) and (c), of at least one organic mono- and/or dicarboxylic acid or anhydrides thereof, e) catalysts, f) blowing agents, and, if desired, g) assistants and/or additives, in a closed mould with compaction, expediently using the low-pressure or preferably reaction injection moulding technique.
