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.
