Full TextAbstract
Transition metal catalysts at the end of the periodic table have attracted a lot of attention for catalytic polymerizations in recent years, because in addition to the catalytic polymerization of non-polar olefins, they have been studied for polymerization of polar monomers such as methyl methacrylate (MMA), as well. In this project, a catalyst of [(1,4-phenylenebis(azaneylylidene)) bis(1-benzylinolin-2-one)] CoCl2, (a dinuclear cobalt (II) catalyst (NCCL)) was synthesized based on phenoxy-imine ligand with 1,4-phenylenediamine bridge, a rigid bridge, for polymerization of MMA. The synthesis reactions were followed with TLC studies. Structures of both ligand and catalyst are studied using FTIR technique. Also, a synthesised modified methyl aluminoxan (MMAO) is used as a co-catalyst for the polymerization. The dinuclear cobalt (II) catalyst was suitable for catalytic polymerization which could be due to the presence of second metal center that give a sufficient activity for the polymerization of MMA. The optimom molar ratio of [Al]/[Co] for this catalyst is 1000:1. This reaction was investigated at ambient temperature (29±1°C) and the highest activity was 2.582 (g PMMA/mmol Co. h).
