    • A stabilizer mixture for one or more compounds of the general formula (1) and (1A) but preferably (1), wherein the groups R independently stand for an alkyl-, cycloalkyl-, aralkyl- or aryl-rest whereas the aromatic ring system may be optionally substituted by one or more groups R' which may be identical or different and which groups R' can be an aryl-, a saturated or unsaturated alkyl-, aralkyl- or cycloalkyl-group as well as halogen, an amino-, aminoalkyl-, aminocycloalkyl-, cyano-, thiocyano- or nitrogroup.and a UV-absorber, hindered amine stabilizer, sterically hindered phenol, organo-phosphite, organophosphonite, organophosphine, or mixtures thereof.The present invention is useful in the protection of various polymeric substrates against the damaging influence of light exposure by the long term storage of polymers. This effect can be observed especially in so-called engineering plastics (such as, for example, PC, PET, PBT, ABS, TPU).
    • 一种或多种通式(1)和(1A)化合物但优选(1)的稳定剂混合物,其中基团R独立地表示烷基 - ,环烷基 - ,芳烷基 - 或芳基 - 芳基,而芳环体系 可以任选地被一个或多个可以相同或不同的基团R'取代,R'可以是芳基,饱和或不饱和的烷基 - ,芳烷基 - 或环烷基 - 基团以及卤素,氨基 - 氨基烷基 - ,氨基环烷基 - ,氰基 - ,氰基 - 氰基 - 或硝基,以及紫外 - 吸收剂,受阻胺稳定剂,空间位阻酚,有机亚磷酸酯,有机亚膦酸酯,有机膦或其混合物。本发明可用于保护各种 聚合物基材通过聚合物的长期储存抵抗光暴露的破坏性影响。 这种效果可以在所谓的工程塑料(例如PC,PET,PBT,ABS,TPU)中被观察到。
