乙丙共聚物的过氧化氢基化反应及其与烯类单体的接枝共聚合

Hydroperoxidation of EP Copolymer and Its Olefine Monomer Grafting Reaction

本文研究了乙丙共聚物在含臭氧的氧气流中的过氧化氢基化反应,考察了温度、时间、浓度以及添加剂等对过氧化氢基化物(EPHP)中过氧化氢基含量的影响;研究了EPHP与苯乙烯类单体进行接枝共聚反应以及接枝产物的共混增韧作用。

Hydroperoxidation of ethylene-propylene copolymer with ozone contained in oxygen stream was investigated. The effects of temperature, concentration, radical-generating agent, additive, and reaction time on hydroperoxyl content were studied. The hydroperoxidation product (EPHP) was used to initiate olefine monomers, such as styrene, etc. for grafting copolymerization and examination of toughening effect of the grafted EP in the blend.
