Abstract
El trabajo de esta Tesis Doctoral con título “Efectos del Confinamiento en las Reacciones de Homopolimerización y Copolimerización en Nanoreactores de Alúmina Porosa (AAO). Cinética de la Reacción, Relaciones de Reactividad y Propiedades del Polímero", tiene como objetivo principal profundizar en el estudio de las reacciones de polimerización en confinamiento utilizando las nanocavidades de AAO como nanoreactores. Los monómeros seleccionados han sido: metacrilato de butilo (BMA), acrilato de 2-hidroxietilo (HEA) y 1-vinil-2-pirrolidona (VP). Para las reacciones de polimerización se han seleccionado dos mecanismos de polimerización principales como: la polimerización por radicales libres (FRP) y la polimerización radical controlada por transferencia de átomo (ATRP). Adicionalmente, se ha realizado la homopolimerización de BMA mediante polimerización radical controlada mediante nitróxidos (NMP). El estudio de la copolimerización en confinamiento se ha llevado a cabo con BMA y HEA, dos monómeros con características complementarias y aplicaciones muy diferentes. Se ha realizado también el estudio de las polimerizaciones en masa como referencia comparativa. Además, el trabajo experimental se completa con el estudio de las propiedades químicas, térmicas y morfológicas del polímero obtenido en confinamiento y en masa...
The principal aim of this Doctoral Thesis work titled “Confinement Effects on Homopolymerization and Copolymerization Reactions in Porous Alumina Nanoreactors (AAO). Kinetics Reaction, Reactivity Relationships and Polymer Properties", is to deepen into the study of polymerization reactions in confinement using AAO nanocavities as nanoreactors. The selected monomers have been: butyl methacrylate (BMA), 2-hydroxyethyl acrylate (HEA) and 1-vinyl-2-pyrrolidone (VP). For polymerization reactions, two main polymerization mechanisms have been selected: free radical polymerization (FRP) and atom transfer radical polymerization (ATRP). Additionally, the homopolymerization of BMA has been carried out by nitroxide-mediated radical polymerization (NMP). The study of confined copolymerization has been accomplished with BMA and HEA, two monomers with complementary characteristics and very different applications. The study of polymerizations in bulk has also been developed as a comparative reference. In addition, the experimental work is completed with the study of the chemical, thermal and morphological properties of the polymer obtained both in confinement and in bulk...
