Process for the preparation of expandable polystyrene |
| 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 an expandable polystyrene obtainable according to such a process and to insulation parts and packaging comprising such an expandable polystyrene. |
