摘要: 本文用IR、NMR、UV以及力学性能测定等方法研究了硬脂酸镍和2,2′-硫代双4-叔辛基酚)并用体系在聚丙烯抗光氧老化中的光防护效果。结果表明,本体系有协同作用,其协同作用的机理可能是本体系在热加工条件下,形成了类似于Am101的镍-硫代双酚的螯合物。

Abstract: The effect of the combination of nickel stearate (NiSt2) and 2, 2’-thiobis-(-4-tert-octylphenol) (TBP) in protecting polypropylene was studied by the way of using IR-, NMR- and UV-spectra and the measurement of mechanical property. It was shown that the NiSt2-TBP combination possesses synergism. The mechanism of the synergic action is supposed to form chelate of niekel-thiobisphenol analogous to Am 101 during heat processing of the polymer.
