求英文翻译为中文，高分子合成方面

| The catalysts of [MnII(TpmiPr,iPr)(Cl)2] and [MnII(TpmiPr,iPr) (Br)(HOMe)2]Br activated by TIBA/TB copolymerized ethylene and 1-hexene. The molecular weight of these copolymers was decreased with increased concentrations of 1-hexene [29]. These results suggest that the polymer forms at the dormant site from insertion of 1-hexene to the active species. The dependence of molecular weight of copolymers on the concentrations of 1-hexene was similar to that of ethylene–-olefin copolymer produced from group 4 metallocene with co-catalyst . |
