Título da palestra: Ethylene Oligo- and Polymerization Promoted by Chromium Complexes Bearing Schiff Base Ligands: Effect of Ligand Architecture on the Activity and Product Distribution 

Resumo do palestrante: Osvaldo L. Casagrande Jr received his PhD degree in Inorganic Chemistry from the Institute of Chemistry, State University of São Paulo- UNESP in 1991. He was visiting professor at Federal University of Rio Grande do Sul (1992-1993), and became Assistant Professor in 1994. From 1996 to 1998 he was a postdoctoral fellow at University of Iowa in the Group of Professor Richard F. Jordan (1996–1998). In 2004 he joined the group of Professor Carpentier (University of Rennes) as visiting professor. He was head of Catalysis Division of the Brazilian Chemical Society from 2004 till 2006. From 2009 – 2013 he was Head of the Post-Graduate Program at the Institute of Chemistry – UFRGS. In 2012 he was promoted to Professor at the Department of Inorganic- Institute of Chemistry /UFRGS. He was a full member (Earth Sciences) of the Advisory Committee of the Postgraduate Pro-Rectorate (2014-2018) and titular member of the Board of the Institute of Chemistry (2017-2021). He is currently a titular member of the Research Council at Federal University of Rio Grande do Sul. His current research mainly focuses on the Organometallic and Coordination Chemistry involving groups 4-6, and 10 to application in oligo- and polymerization processes and production of polyethylene nanocomposites via polymerization-filling technique. Since 2000 he has developing research projects supported by petrochemical companies such as Braskem S/A, Petrobras S/A and Shell.Osvaldo L.
