Abstract

The present invention relates to a process for the preparation of expandable polystyrene comprising the following steps: - i) heating an aqueous suspension comprising styrene monomer and at least one organic peroxide initiator of formula (I) 1-alkoxy-1-t-alkylperoxycyclohexane in which the alkoxy group contains 1 to 4 carbon atoms  the t-alkyl group contains 4 to 12 carbon atoms  and the cyclohexane ring may optionally be substituted with 1 to 3 alkyl groups each  independently having 1 to 3 carbon atoms  at a temperature ranging from 100°C to 120°C  - ii) adding a blowing agent selected from the group consisting of alkanes having from 4 to 6 carbon atoms and mixtures thereof. The invention also relates to expandable polystyrene obtainable according to such a process and to insulation parts and packaging comprising such expandable polystyrene.
