Introduction

CH355 为无色至淡黄色透明液体,属于二烷基型有机过氧化物。主要用于乙烯、苯乙烯、丙烯腈、丙烯酸酯及甲基丙烯酸酯的聚合与共聚反应,作为中高温自由基引发剂,具有良好的热稳定性和可控分解特性。

CH355 is a colorless to slightly yellow transparent liquid. It belongs to dialkyl-type organic peroxide. It is widely used as a medium- to high-temperature free-radical initiator for the polymerization and copolymerization of ethylene, styrene, acrylonitrile, acrylate and methyl acrylate, offering good thermal stability and controlled decomposition behavior.
