| 摘 要： | Novel copolymerization of ethylene with substituted allenes(CH_2=C = CH—R,1:R = n-butyl,2:R =n-octyl) using bis(β-enaminoketonato)titanium catalystsPhN = C(R_2)CHC(R_1)O]_2TiCl_2(1a:R_1 = CF_3,R_2 = CH_3;1b:R_1 = Ph,R_2 = CF_3) has been investigated.In the presence of modified methylaluminoxane,these catalysts can copolymerize ethylene with substituted allenes,affording copolymers with unimodal molecular weight distributions and homogeneous compositions.By varying the reaction conditions,the comonomer i...
