Theoretical and experimental study on the phase inversion process during the bulk synthesis of high impact polystyrene
(2021-03-26) Maffi, Juan M.; Estenoz, Diana; Berkenwald, Emilio
"In this thesis, the phenomenon of phase inversion is studied from a qualitative, theoretical and experimental point of view. The general objective is to contribute to the understanding of this fuid- and thermodynamic phenomenon in its particular application in the case of HIPS. The aim is to develop a physical-mathematical model capable of predicting the point of phase inversion during the reaction from the reactor conditions. Among the different alternatives, approaches based on the rheological evolution of the reaction mixture and others based on the fuid dynamics of the dispersed system are explored."
