摘要

Various (anilide)(cyclopentadienyl)titanium(IV) complexes of type, Cp'MCl_2[N(2,6-Me_2C_6H_3)-(SiMe_3)] [M = Ti and Cp' = C_5Me_5 (Cp~*, 1), l,3-Me_2C_5H_3 (2), C_5H_5 (Cp, 3); M = Zr and Cp' = Cp~* (4)], have been cliosen for polymerization of ethylene, propylene, and styrene in the presence of methylaluminoxane (MAO). 1 was found to exhibit the highest catalytic activity for ethylene polymerization whereas 3 showed the highest catalytic activity for syndiospecific styrene polymerization. These results clearly show that efficient catalyst for the desired polymerization can be modified only by changing the substituent on cyclopentadienyl group.
