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: Oligomeric carbodiimides having an average degree of condensation of from 2 to 30, obtainable by oligocondensation of a) from 40 to 100 mol % of 2,4'-diisocyanatodiphenylmethane or of a 3,3',5,5'-tetra-C1-C4-alkyl-4,4'-diisocyanatodiphenylmethane and b) from 0 to 60 mol % of a further bi- or polyfunctional aromatic isocyanate and c) if desired, complete or partial reaction of the remaining free isocyanate groups of the oligomers with an aliphatic, araliphatic or cycloaliphatic alcohol or amine, are used mainly for stabilizing polyester-containing polyurethanes against hydrolytic degradation.

IPC: C08K5/353
Abstract: Elastomers (I) with bound ester and urethane gps. contain on (I) 0.1-10% (all pts.wt.) of at least one phenylenebisoxazoline (II) of formula (A) and/or (B), where R1-R3 (same or different) are H, Ph or 1-5C alkyl. Also claimed is the prepn. of polyurethanes (III) contg. bound ester gps. by reacting (A) organic polyisocyanates with (B) higher molecular at least difunctional, polyesterols and (C) chain lengthening agents and/or crosslinking agents in presence of (D) a (II), opt. in presence of (E) blowing agents, (F) catalysts, (G) auxiliaries and/or additives. USE/ADVANTAGE - Used as moulded articles, partic. in machinery construction and transport industries, esp. as flexible pipes, skins, sheets, spring elements, buffers and top coats; foams in furniture, household appts., shoe and motor car industries, e.g. in seats, insulating or cladding materials, sun blinds, head rests, shoe soles, ski cores and receptacles for skis. (I) and (III) have improved hydrolysis resistance and mechanical properties (partic. tensile strength, extension to break), (II) are soluble in starting materials or can be readily incorporated in (I) granulate, do not affect morphology of (I) or (III) and do not migrate.
