据《Polym.Degrad.Stab.》1997,58,261～268报道,法国化学家将聚丙烯(PP)置于不同强度的入射光下(λ≥300nm的多色光)进行光氧化研究.试验中不改变光源的相对光谱分布或暴露试样的表面温度.暴露后的PP薄膜经FTIR分析作出氧化曲线,并作出诱导期和氧化的稳定态速率对
According to “Polym.Degrad.Stab.” 1997,58,261 ~ 268 reported that French chemists polypropylene (PP) under different intensities of incident light (λ ≥ 300nm multi-color light) for photooxidation studies .This experiment does not change Relative spectral distribution of the light source or exposed surface temperature of the sample.The exposed PP film was subjected to an FTIR analysis to make an oxidation curve and a steady state rate of induction and oxidation
