The copolymerization of norbornene (NB) and divinylbenzene (DVB) was carried out using anilinonaphthoquinone‐ligated nickel complexes of the type [Ni(C10H5O2NAr)(Ph)(PPh3)] (1a: Ar = C6H3‐2,6‐ iPr; 1b: Ar = C6H2‐2,4,6‐Me; 1c: Ar = C6H5) with modified methylaluminoxane (MMAO) as a cocatalyst. The DVB content was varied (5–25 mol%) and the resulting copolymers exhibited number‐average molecular weights (Mn) of 40,000–69,000 g/mol with polydispersities (PDI = 1.5–1.8). The styryl group of the NB/DVB copolymer was used for grafting poly(methyl methacrylate) by reverse atom transfer radical polymerization using azobisisobutyronitrile in the presence of copper chloride and bipyridine.

苯并萘并萘醌连接的镍配合物催化降冰片烯/二乙烯基苯共聚物的合成及其在接枝聚合物合成中的应用

降冰片烯(NB)和二乙烯基苯(DVB)的共聚反应是使用[Ni(C 10 H 5 O 2 NAr)(Ph)(PPh 3)](1a:Ar = C 6 ħ 3 -2,6-镨;图1b:氩= C 6 H ^ 2 -2,4,6-我; 1C:氩= C 6 H ^ 5)与改性甲基(MMAO)作为助催化剂。DVB含量变化(5-25 mol%),所得共聚物表现出数均分子量(M n )40,000–69,000 g / mol,具有多分散性(PDI = 1.5–1.8)。NB / DVB共聚物的苯乙烯基用于在氯化铜和联吡啶存在下,通过偶氮二异丁腈通过反向原子转移自由基聚合反应接枝聚甲基丙烯酸甲酯。
