New advances in the mathematical modeling of the continuous bulk process for the production of high-impact polystyrene using multifunctional initiators

"New advances in the mathematical modeling of the bulk continuous high-impact polystyrene (HIPS) process are presented. The model consists of three modules that allow the simulation of: (1) a polymerization reactor train, (2) a devolatilization (DV) stage, and (3) structure–properties relations...
