tesis de doctorado.listelement.badge Mathematical modeling of discontinuous bulk styrene polymerization processes using multifunctional initiators(2016) Berkenwald, Emilio; Estenoz, Diana; Marqués, Dardo"En esta tesis, se estudia el uso de iniciadores multifuncionales para la polimerización en masa de estireno. El objetivo general es desarrollar modelos matemáticos detallados, y a la vez genéricos, que permitan describir la compleja fisicoquímica de estos procesos y predecir las variables principales de polimerizacióon, la evolución de la estructura molecular y las caracteríticas físicas del producto obtenido. La labor teórica se complementa con trabajos experimentales que permiten ajustar y validar los modelos propuestos."tesis de doctorado.listelement.badge 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."
