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: A prodn. process for mfg. foamed plastic products involves: (a) feeding material into a closed tool (1) and after a reaction time, (b) demoulding the product. The process is effected in tools mounted on carriers on a conveyor and demoulding of products is effected by an extraction unit (11) which is moved up to each tool (1) in turn to open the latter (1) and remove the product. Also claimed is process appts. including the demoulding unit (11).

Abstract: A process is disclosed for preparing compact and preferably cellular polyurethane elastomers by reacting: (a) high-molecular polyhydroxyl compounds and optionally (b) low-molecular chain-lengthening and/or cross-linking agents with (c) 1,4-phenylene diisocyanate (p-PDI) and at least one additional aromatic diisocyanate selected from the group of toluylene-diisocyanate, diphenylmethane-diisocyanate, 3,3'dimethyl-diphenyl-diisocyanate, 1,2-diphenylethane-diisocyanate and/or an aliphatic diisocyanate with 4 to 12 carbon atoms and/or a cycloaliphatic diisocyanate with 6 to 18 carbon atoms, in the presence or absence of (d) catalysts; (e) foaming agents; and (f) additives. Components (a), (c) and optionally (c) are preferably reacted after their prepolymerisation. Also disclosed are isocyanate prepolymers suitable for preparing these elastomers.
