Modelling of high-impact polystyrene evolution using the Cahn-Hilliard approach
Original language description
The high-impact polystyrene (HIPS) is produced by the free radical polymerization of styrene in the presence of polybutadiene (PB). The formed PS is highly incompatible with the PB. At low conversion of styrene a phase separation takes place by mechanisms of nucleation or spinodal decomposition. The emerging phases are in thermodynamic equlibrium but increasing amount of PS in the system, grafting of the styrene onto the PB backbone, stirring of the mixture and interfacial forces lead to further morphology evolution. The morphology of HIPS can be desribed on two levels, (i) the micron sized PB domains distributed through the continuous PS phase, (ii) submicron PS occlusions inside the PB domains. This morphology is also known as the "salami" morphology. The model is based upon the modified Cahn-Hilliard equations and attempts to qualitatively describe the morphology evolution of the "salami" morphology of HIPS. Our model takes into account the reaction of styrene, polymer grafting, she
