摘要：

Organic phosphites combined with Hindered Amine Light Stabilizers (HALS) were used as stabilizers in the photo- and thermoxidation of polypropylene film. The efficiency of the mixture of HALS and phosphite was compared with the efficiency of the combination of HALS and phosphite in one molecule. A strong synergistic effect was observed for the molecule with HALS and phosphite moieties. Generally, the mixture of HALS and phosphite exhibited synergistic, antagonistic or additive effects. The efficiency of the mixture depends upon the chemical structure of the phosphite and HALS structural units as well as on the ratio of the components.
