In relation to the bulk high‐impact polystyrene process, this work investigates the partition between phases of styrene and an initiator: tert‐ butyl peroctoate. A Flory‐Huggins model was applied for predicting the phase separation point and the partitions of styrene and tert‐ butyl peroctoate. For...
