## Abstract CHβtype catalysts were prepared by reacting MgCl~2~ Β· ROH, where ROH is 2βethyl hexanol (EH), (R)β2βoctanol (Rβ20), and (S)β2βoctanol (Sβ20), with TiCl~4~ in the presence of diβ__i__βbutyl phthalate (BP), diβ__i__βbutyl terephthalate (BT), (β)βdimenthyl phthalate (MP), or (β)βdimenthyl
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
