EnglishThis report describes propylene polymerization reactions with titanium complexes bearing carbamato ligands,Ti(O2CNMe2)Cl2 (I) and Ti(O2CR2)4 [R25NMe2 (II), NEt2 (III) and(IV)]. Combinations of these complexes and MAOform catalysts for the synthesis of atactic polypropylene, as confirmed by FT-IR, DSC and 13C NMR analysis. Effects of main reaction parameters on the catalyst activity were studied including the type of complex, solvent, temperature, and the [Al]/[Ti] molar ratio. The highest activity was observed when chlorobenzene was used as a solvent and AlMe3- depleted MAO was employed as a cocatalyst
