Abstract

Bulk polymerization of styrene was carried out at 100°C using initiators of ester group-containing peroxides such as t-butylperoxy benzoate, t-butylperoxy isopropyl carbonate, and t-butylperoxy phenyl carbonate which had approximately equal decomposition temperatures, and analyzed by the kinetic method and the simulation to high conversion. The behavior of the polymerization was influenced significantly by the kind of primary radicals with various reactivities. Particularly, the hydrogen atom abstraction from the polymer by the alkoxy radicals and the primary radical termination by stable phenoxy radicals influenced greatly the rates and the molecular weight of the polymer formed in the latter half stage.
