摘要
维生素E通过和自由基发生反应而实现抗氧性,聚丙烯(PP)的氧化过程中会产生过氧自由基、烷氧自由基、羟自由基,而维生素E正是通过捕获自由基,使氧化的链式反应终结。同时,通过几组数据表明,如在维生素E中加入辅助抗氧剂,可使维生素E的抗氧效果更佳,并可改善PP成型的缺陷。
Vitamin E has realized the anti -oxygen through reaction with free radical,Polypropylene（PP） will produce the oxygen radical, the alkane oxygen radical and hydroxy radical wthen it is oxidized. Vitamin E ends oxidation chain reaction though capturing free radical. Several groups of data indicated that the Vitamin E oxidation resistance＇s effect would become better if joining the auxiliary antioxidant. Meanwhile ,The flaw could improve during its processed time.
