摘要 研究了不同光谱范围的聚丙烯氧化过程的化学发光动力学特性。研究表明,聚丙烯氧化过程的化学发光分属于两个光谱范围,有三个峰值过程。第一和第三个峰值过程在530到725nm光谱范围依次出现;第二个峰值过程仅在330到590nm光谱范围观测到;530到590nm光谱范围则可观测到所涉及的三个峰值过程。其中,第一个峰值过程与试样的氧化程度有关,第二和第三个峰值过程对应于自催化氧化反应。文中还讨论了聚丙烯氧化过程的化学发光机制。 The chemiluminescence kinetic properties were studied in the different spectral regions during oxidation of polypropylene. It is shown that the chemiluminescence from oxidation of polypropylene belongs to both spectral regions in which there are three peak processes. The processes of the first and the third peak were observed in the 530-725 nm region successively. The process of the second peak can only be observed in the 330-590 nm region. All of the three processes were observed in the 530-590 nm region. Among the three processes, the first peak process is related to the degree of oxidation of the sample, and the second and the third peak processes correspond to autocatalytic oxidation reaction. Then the possible chemiluminescence mechanism is discussed during oxidation of polypropylene.
