Effect of para-Substituents in Ethylene Copolymerizations with 1-Decene, 1-Dodecene, and with 2-Methyl-1-Pentene Using Phenoxide Modified Half-Titanocenes-MAO Catalyst Systems.

ABSTRACT: Effect of para-substituents in the ethylene (E) copolymerization with 1-decene (DC), 1-dodecene (DD), and with 2-methyl-1-pentene (2M1P) using a series of Cp*TiCl₂ (O-2,6-ⁱ Pr₂ -4-R-C₆ H₂ ) [R=H (1), ^t Bu (2), Ph (3), CHPh₂ (4), CPh₃ (5), SiMe₃ (6), SiEt₃ (7), and newly prepared 4-^t BuC₆ H₄ (8) and 3,5-Me₂ C₆ H₃ (9)]-MAO catalyst systems has been studied. The activities in these copolymerization reactions were affected by the para-substituent, and the SiMe₃ (6), SiEt₃ (7) and 3,5-Me₂ C₆ H₃ (9) analogues showed the higher activities at 50 °C in the E copolymerizat
