By use of a THF-containing trimethylsilylmethyl scandium catalyst system (C5Me4SiMe3)Sc(CH2SiMe3)2(THF)/[Ph3C][B(C6F5)4], the multi-component copolymerization of 10-bromo-1-decene (BrDC) with ethylene, propylene, and dienes has been achieved to afford a new family of bromine-functionalized polyolefins with controllable composition and high molecular weight. The copolymerization of BrDC with ethylene afforded the well-defined BrDC–ethylene copolymers with high BrDC incorporation (up to 12 mol%) and high molecular weight (Mw > 100 kg mol−1). The terpolymerization of propylene, ethylene with BrDC afforded random ethylene–propylene–BrDC terpolymers with controllable bromine content (2 ~ 11 mol%), high molecular weight (Mw > 100 kg mol−1) and low glass transition temperature (Tg = −51 °C ~ −67 °C). Moreover, the tetrapolymerization of ethylene, propylene, BrDC, and ethylidene norbornene or conjugated dienes such as isoprene and myrcene has been achieved for the first time to afford selectively the bromine-functionalized ethylene–propylene–diene rubbers containing various types of double bonds.

通过使用含 THF 的三甲基甲硅烷基甲基钪催化剂体系 (C 5 Me 4 SiMe 3 )Sc(CH 2 SiMe 3 ) 2 (THF)/[Ph 3 C][B(C 6 F 5 ) 4 ]， 10-溴-1-癸烯（BrDC）与乙烯、丙烯和二烯的组分共聚已经实现，以提供具有可控组成和高分子量的溴官能化聚烯烃的新家族。BrDC 与乙烯的共聚提供了明确的 BrDC-乙烯共聚物，具有高 BrDC 掺入（高达 12 mol%）和高分子量（M w > 100 kg mol-1 )。丙烯、乙烯与 BrDC 的三元聚合得到无规乙烯-丙烯-BrDC 三元共聚物，其溴含量可控（2 ~ 11 mol%）、高分子量（M w > 100 kg mol -1）和低玻璃化转变温度（T g = −51 °C ~ −67 °C)。此外，首次实现了乙烯、丙烯、BrDC 和亚乙基降冰片烯或共轭二烯（如异戊二烯和月桂烯）的四聚反应，以选择性地提供含有各种类型双键的溴官能化乙烯-丙烯-二烯橡胶。
