Abstract:
The invention relates to a suspension polymerization process for the preparation of styrene-containing (co)polymers, wherein the process comprises the steps of continuously or semi-continuously dosing an initiator to the reaction mixture, said initiator having a specified half-life at the temperature of the reaction mixture to which it is dosed. The invention further relates to styrene based (co)polymer obtainable by said process, and to the use of said styrene (co)polymer in a shaping process.

Abstract:
The present invention relates to peroxide compositions comprising one or more cyclic ketone peroxides, one or more dialkyl peroxides, and, optionally, one or more conventional phlegmatisers. These compositions are safe and storage stable. In addition, the invention also pertains to the use of such compositions in polymerization and (co)polymer modification processes.
