are as defined in claim 1, can be used, in combination with sterically hindered amines of the polyalkylpiperidine type, for stabilizing organic polymers. Some of these compounds are novel and can also be used without polyalkylpiperidine.
公式I1中,n为1至4,R1至R7如权利要求1所定义的o-羟基苯基-s-三嗪可以与聚烷基
哌啶型的立体阻碍胺一起用于稳定有机聚合物。其中一些化合物是新颖的,也可以在没有聚烷基
哌啶的情况下使用。
