Stabilisation pf polycondensation polymers against hydrolytic degradation through a combination of aziridines and acid scavengers
Patent profile:
The present invention relates to a new stabilizer composition on the basis of an aziridine and at least a hydrotalcite, zeolite, dawsonite or mixtures thereof. The stabilizer composition is suitable for stabilizing condensation polymers, in particular aliphatic polyesters against hydrolytic degradation. The invention also relates to the use of the stabilizer composition, a method for stabilizing condensation polymers against hydrolytic degradation and mouldings thereof.
