Formation of anthracene cation radicals from 9,10-dihydro-9,10-epidioxyanthracene derivatives; peroxide-initiated cationic polymerization of styrene in liquid sulphur dioxide

Abstract

The formation of anthracene cation radicals from some 9,10-dihydro-9,10-epidioxyanthracene derivatives in liquid sulphur dioxide is reported. By use of catalytic amounts of 9,10-dihydro-9,10-epidioxyanthracenes, the cationic polymerization of styrene has been accomplished in liquid sulphur dioxide.
