Process for stabilizing plastics containing ester groups
摘要:
The invention relates to a process for stabilizing ester-containing plastics against degradation by heat and/or hydrolysis by the incorporation of sterically hindered isocyanate-terminated carbodiimides. The incorporable carbodiimides produce an excellent anti-aging effect and do not give rise to volatile products, even at very high temperatures.
