摘要：

The combination of structural elements of phenols, phosphites or phosphonites and hindered amine light stabilizers (HALS) has led to so-called HALS-phosph(on)ites. These polyfunctional antioxidants contain in their molecules ROOH decomposing, chain breaking and light stabilizing moieties. The synthesis and the antioxidant activity of such compounds are described. Aromatic esters of phosphonic and phosphonous acid with two identical piperidyl substituents show a pronounced hydrolytic resistance and a high efficiency against thermooxidative and photooxidative degradation of polyether polyols, cumene and polypropylene.
