Abstract: Vinyl chloride is polymerized in aqueous suspension at temperatures between 35* and 75 *C at a pH of less than 8.0 and in the presence of an initiator system in which acetyl cyclohexane sulfonyl peroxide is mixed either with t-butyl perpivalate or with di-isopropyl percarbonate. The product may be used like conventional polyvinyl chloride as a plastics material.
Abstract translation: 氯乙烯在含水悬浮液中在温度为35〜75℃，pH小于8.0的条件下，在引发剂体系存在下，乙酰基环己烷磺酰过氧化物与新戊酸叔丁酯或二异丙基 过碳酸盐 该产品可以像常规聚氯乙烯一样用作塑料材料。
