Short Abstract: Organocatalysis has become a very powerful tool for polymer chemistry, as judged by the number of articles published in this field in the past decade. A variety of small organic mole-cules, including Brønsted/Lewis bases and acids, based on sulfonic acids, phosphoric acids, amines, phosphines or carbenes, but also on bi-component systems, have been employed as catalyst for the polymerization of miscellaneous monomers.1 One of the key reasons for transi-tioning to organocatalysis is their ability to be effectively removed from the final polymers in comparison to their metallic counterparts which are exceedingly difficult to remove. This fact is driving not only their utilization in some residual catalyst sensitive applications such as bio-medical or microelectronics but also their investigation in commodity polymers to facilitate their recycling.2

In this lecture, some specific examples from our group about the use of organocatalysis in different applications will be described.3 Later, we will explore how organocatalysis enables the preparation of unique polymer architectures that allow us to use these polymers in diverse applications such as polymer for energy or in the biomediacal field.4 To finish this lecture we will emphasized the activities of our group in polymer recycling.5
