许多高聚物氧化过程会伴随化学发光,研究表明,光发射主要是由氢过氧化物的分解和烷基过氧基的结合所产生的,高密度聚乙烯的氧化按游离基链式反应机理进行,氢过氧化物的积聚和分解,烷基过氧基的结合,是游离基链式反应的重要历程,因此,化学发光方法提供了研究高密度聚乙烯氧化的一种新手段。 Many polymer oxidation processes are accompanied by chemiluminescence. Studies have shown that light emission is mainly caused by the decomposition of hydroperoxides and the combination of alkylperoxy groups. The oxidation of HDPE is catalyzed by a free radical chain reaction mechanism , The accumulation and decomposition of hydroperoxides, the combination of alkyl peroxy groups, is an important course of the free radical chain reaction. Therefore, the chemiluminescence method provides a new means to study the oxidation of high density polyethylene.
