1. A method for stabilizing polymers containing ester groups, characterized in that carbodiimides of the formula (I) where R1, R2, R4 and R6 is each independently C3-C6-alkyl and R3 and R5 is each independently C1-C3alkyl, are added in liquid form (liquid-dosed) in continuous or batch wise processes for preparation and/or processing thereof. |
