After a long period of contribution, and hard work, for our journal Polímeros: Ciência e Tecnologia Prof. Adhemar Collà Ruvolo Filho is retiring. The pathways of Polímeros and of Prof. Adhemar crossed during many years. He had active participation in the journal’s consolidation since its creation. He markedly contributed to maintain the scientific level and periodicity of the journal. Joined the Editorial Council and Editorial Committee in 2003, and always participated actively in the discussions and decisions taken by these commissions. His suggestions were well accepted and his participation in the debates was serene and conclusive. In 2006, he accepted the task to become Editor in Chief of the journal. At that time, the journal was setting feet in the national and international scientific scenario and he played an important role for these actions up to 2011. From 2015 to 2016, he acted as provisional Editor in Chief. After that, he was an active member of the Editorial Committee, with a strong position favorable to the peer review system, participating himself in the system as a careful referee. In the period from 2006 to 2018 Prof Adhemar had 14 papers accepted for publication in Polímeros, the last one in volume 28^[1].

The Brazilian Polymer Association (Associação Brasileira de Polímeros, ABPol), The Editorial Council of “Polímeros: Ciência e Tecnologia” and all the polymer Science community, acknowledge the contribution of Prof. Adhemar and wish him productive fishing expeditions in the future.
