Resum:
In this thesis, progress has been made in the study of recyclable polythiourethane (PTU) thermosetting networks, due to the dynamic exchange between thiourethane groups. The materials have been prepared by reaction between polyfunctional thiols and isocyanates, both under acidic and basic conditions. In addition, the applications of these materials as recyclable and self-healing materials and as matrix composite have been studied. In search of a greater sustainability, the catalytic activity of alternatives to tin (IV) compounds, the most widely used at an industrial level, has been studied. Different thiols have also been prepared from biomass derivatives, and their role as a substitute for thiols derived from fossil fuels has been studied.
