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 thermoplastic molding material consists of from 10 to 90 parts by weight of a polycarbonate A and from 90 to 10 parts by weight of a graft copolymer B having a mean particle size of from 200 to 700 nm (d50 value of the integral mass distribution). The graft polymer B is formed from an elastomer (rubber) (b1), which accounts for from 10 to 80% by weight, and a grafted shell (b2), which accounts for from 90 to 20% by weight, the percentages in each case being based on (B). The elastomer (b1) is composed of from 50 to 99.9% by weight of an alkyl acrylate, where alkyl is of 1 to 8 carbon atoms, and from 0.1 to 5% by weight of a copolymerizable polyfunctional crosslinking monomer. The grafted shell (b2) is produced in three stages and contains, as graft monomers, (b2a1) from 5 to 40% by weight of a monoethylenically unsaturated aromatic hydrocarbon of not more than 12 carbon atoms, in the first stage, (b2a2) from 15 to 50% by weight of a mixture of a monoethylenically unsaturated aromatic hydrocarbon of not more than 12 carbon atoms and a copolymerizable ethylenically unsaturated monomer, in a weight ratio of from 90:10 to 60:40, in the second stage, and (b2a3) from 10 to 85% by weight of an alkyl (meth)acrylate in the third stage, the percentages in each case being based on (b2).
