摘要：
Ethylene copolymerizations with 2-methyl-1-pentene, 1-dodecene (DD), vinylcyclohexane (VCH), [Me2Si(C5Me4)((NBu)-Bu-t)]TiCl2 (1), Cp*TiMe2(O-2,6-Pr-i(2)-4-RC6H2) [R = H (2), SiEt3 (3)]-borate, and [A(H)](+)[BAr4](-) [Ar = C6F5; A(H)(+) = N+(H)Me(n-C18H37)(2), N+(H)(CH2CF3)(n-C18H37)(2), HO+(n-C14H29)(2)center dot O(n-C14H29)(2), HO+(n-C16H33)(2)center dot O(n-C16H33)(2); Ar = C10F7, A(H)(+) = HO+(n-C14H29)(2)center dot O(n-C14H29)(2) (B5), N+(H)(CH2CF3)(n-C18H37)(2)] catalyst systems conducted in methylcyclohexane (MCH) exhibited better comonomer incorporation than those conducted in toluene (in the presence of methylaluminoxane (MAO) or borate cocatalysts). The activity was affected by the borate cocatalyst and 1,3-B5 catalyst systems in MCH and showed the highest activity in the ethylene copolymerizations with VCH and DD.
