Abstract: The invention concerns impact-resistant thermoplastic shaping compounds containing: A) 10 to 99.5 wt % of a thermoplastic polymer from the group comprising polyoxymethylenes, polyolefins, polyesters, polycarbonates, polystyrene, ABS, ASA, SAN, polyamides or poly(meth)acrylates or their mixtures; B) 0.5 to 80 wt % of a thermoplastic polyurethane; C) 0 to 50 wt % of a fibrous or particulate filler; and D) 0 to 30 wt % of conventional additives and processing agents; the thermoplastic polyurethane B) containing 0.05 to 10 wt %, relative to B), of a carbodiimide of formula (I), in which R, which is the same or different, is selected from the group comprising -NCO-, -NHCONHR -, -NHCONR R - and -NHCOOR residues, wherein R and R are the same or different and represent an alkyl, cycloalkyl or aralkyl residue; and R is identical to R or is an alkoxypolyoxyalkylene residue; and n is an integer from 0 to 10.

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.
