The kinetics of propylene polymerization initiated by ansa-metallocene diamide compound rac-(EBI)Hf(NMe 2 ) 2 (EBI Ο­ C 2 H 4 -(indenyl) 2 , rac-1) were investigated. The rac-1 compound could be directly utilized for catalyst formations without converting to a dihalide or dialkyl complex in the prese
