Abstract

Free radicals generated from a number of olefinic, acetylenic, and vinyl monomers in the presence of sulphur dioxide and tert‐butyl hydroperoxide were investigated. In all reaction systems a sulphonyl propagating radical first appears which depropagates into the corresponding carbon radical at higher temperatures. The sulphonyl radicals were observed between −119 and −44°C, whereas the carbon radicals were observed from −63 to −1°C. The order of decreasing reactivity of the reaction system was: 3‐hexyne > 1‐heptene > methyl acrylate > acrylonitrile > 1‐heptyne. © 1993 John Wiley & Sons, Inc.
