摘要 以偶氮二异丁腈为引发剂、S-十二烷基-S′-(α,α′-二甲基-α″-乙酸)-三硫代碳酸酯为链转移剂,通过可逆加成-断裂链转移自由基聚合(RAFT)方法,制备了聚甲基丙烯酸甲酯PMMA-CTA大分子链转移剂,在大分子链转移剂的作用下,依次引发甲基丙烯酸丁酯(BMA)、甲基丙烯酸二甲胺乙酯(DMAEMA)聚合,合成了相对分子质量分布指数为1.32的三嵌段共聚物——聚甲基丙烯酸甲酯-b-聚甲基丙烯酸丁酯-b-聚甲基丙烯酸二甲胺乙酯(PMMA205-b-PBMA136-b-PDMAEMA128,下标为聚合度),采用核磁共振氢谱仪、傅里叶变换红外光谱仪对共聚物的结构进行了表征。将共聚物与溴代正丁烷发生季铵化反应,再分别与氟硼酸钠(NaBF4)、双三氟甲基磺酰亚胺锂(LiTFSI)进行阴离子交换,得到含有不同反离子(Br-、BF-4、TFSI-)的三嵌段聚合离子液体共聚物PMMA-b-PBMA-b-PILS。电化学交流阻抗方法测定PMMA-b-PBMA-b-PILS的离子电导率为1×10-2S/cm。

Abstract: Macro-RAFT agent,poly(methyl methacrylate) was synthesized by reversible addition-fragmentation chain transfer(RAFT) polymerization using S-dodecyl-S′-(α,α′-dimethyl-α″-acetic acid)-trithiocarbonate as the chain transfer agent,AIBN as the initiator.PMMA205-b-PBMA136-b-PDMAEMA128(poly(methyl methacrylate)-b-poly(butyl methacrylate)-b-poly(2-(dimethy lamino)ethyl meth-acrylate)(subscript was polymerization degree),triblock copolymer was synthesized by a sequentially initiating of BMA and DMAEMA,in the precence of macro-RAFT agent.Index of molecular weight distribution of triblock copolymer was 1.32.The triblock copolymer was also characterized by 1H-NMR and FT-IR.Then,triblock ionic liquid copolymers with different counterion(Br-,BF-4,TFSI-) were synthesized by the quaternary ammonium reaction with bromobutane and then anion-exchange with Lithium bis (trifluoromethanesulphonyl) imide (LiTFSI) or sodium fluoborate (NaBF4).The electroconductivity of triblock ionic liquid copolymers was also studied by AC impedance,PMMA-b-PBMA-b-PILS membranes showed the ionic conductivity was up to 10-3S/cm at room temperature.
