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 kinetics of polypropylene oxidation in different spectral ranges was studied. Studies have shown that the chemiluminescence of the polypropylene oxidation process belongs to two spectral ranges and has three peak processes. The first and third peak processes occur sequentially in the spectral range 530 to 725 nm; the second peak process is observed only in the 330 to 590 nm spectral range; and the 530 to 590 nm spectral range shows the three peak processes involved. Among them, the first peak process is related to the degree of oxidation of the sample, and the second and third peak processes correspond to the autocatalytic oxidation reaction. The paper also discusses the chemiluminescence mechanism of polypropylene oxidation process.
