采用双(β-酮萘胺)镍(II)、B(C6F5)3及AlEt3三元催化体系催化降冰片烯(NB)及5-降冰片烯-2-甲醇(NB-CH2OH)的加成聚合,合成聚(降冰片烯-co-降冰片烯基甲醇)(PNB-OH)。通过PNB-OH与2-溴-异丁酰溴反应合成Br-PNB,以引发与对苯乙烯磺酸钠(SSA)或甲基丙烯酰氧丙基磺酸钾(SPMA)的原子转移自由基聚合(ATRP),得到以聚降冰片烯为主链的侧链含磺酸基团的接枝共聚物。所有的聚合物有良好的热稳定性,且PNB-g-PSPMA的离子交换容量(IEC)值达到0.787meq/g,PNB-g-PSSA的IEC为1.05meq/g。
Addition of norbornene (NB) and 5-norbornene-2-methanol (NB-CH2OH) catalyzed by nickel (II), nickel (II), B (C6F5) 3 and AlEt3 Poly (norbornene-co-norbornenemethanol) (PNB-OH) was polymerized. Br-PNB was synthesized by reaction of PNB-OH with 2-bromo-isobutyryl bromide to initiate atom transfer free radicals with sodium p-styrene sulfonate (SSA) or potassium methacryloyloxypropyl sulfonate (SPMA) Polymerization (ATRP) to obtain polynorbornene -based side chain sulfonic acid group-containing graft copolymer. All polymers showed good thermal stability with an ion exchange capacity (IEC) value of 0.787 meq / g for PNB-g-PSPMA and 1.05 meq / g for PNB-g-PSSA.
