Investigation and possibility of reduction of styrene monomer in polystyrene produced with GPPS and HIPS grades in the operating unit

In this study, the possibility of further reducing the amount of styrene monomers remaining in the product of ordinary and resistant polystyrene in the operating unit was investigated and the effect of vacuum pressure on evaporator tanks, and amount of water injected into the polymer content before entering the evaporator tanks, and polymer volume in Evaporative tanks and polymer temperature and the effect of operating parameters of polymerization and processing reactors on the amount of residual monomer have been studied and investigated. Also, the performance of the mechanism of evaporative tanks has been investigated and finally a conclusion has been made to optimize and reduce the styrene monomer. In the following, technical and practical suggestions for the necessary modifications based on the above are presented .
