Abstract
The invention relates to hydrolysis-stabilized polyethylene terephthalate (PET)- and/or polylactic acid (PLA)-containing compositions comprising monomeric carbodiimides of the formula (I) where R1, R2, R4 and R6=ethyl and where R3, R5 are each independently C1-C6-alkyl, and to processes for preparation of and to the use of these carbodiimides.
