Polymerization Catalysts Department

Working area:

The main aim of this department carry out basic research on preparation of three types of transition metal based catalysts, for olefin polymerization. These catalysts which are based on mono and bi-supported Ziegler-Natta , metallocen and late transition metals catalysts. The first two types of catalysts are widely used for the manufacturing of a large variety of polymers including polyethylene, isotactic polypropylene and copolymers of ethylene and propylene. Late transition metals catalysts which allow the combination of polar monomers with non polar olefins and thus lead to innovative materials.
