摘要:
通过可逆加成断裂链转移（RAFT）聚合和Cu催化炔基-叠氮环加成反应（CuAAC），合成出了苯乙烯（St）和丙烯酸丁酯（BA）的多嵌段共聚物。首先用双炔基三硫代碳酸酯S,S′-双（α,α′-二甲基-α″-炔丙基乙酸酯基）三硫代酸酯（BPTTC）作为RAFT试剂，进行苯乙烯的聚合。然后丙烯酸丁酯和苯乙烯嵌段共聚，得到聚（苯乙烯-b-丙烯酸丁酯-b-苯乙烯）三嵌段共聚物。最后，三嵌段共聚物和等物质的量的1,5-二叠氮戊烷反应得到（ABA）n型多嵌段共聚物。聚合物通过1H NMR和GPC测试方法表征。根据偶联反应前后的聚合物数均相对分子质量计算，平均重复嵌段的数量DPn可达到27。
Abstract:
Multiblock copolymers of styrene and butyl acrylate were synthesized via RAFT polymerization and Cu catalyzed azide-alkyne cycloaddition. At first, styrene was polymerized using a novel RAFT agent with two alkyne groups, S,S′-bis(α,α′-dimethyl-α″-propargyl acetate) trithiocarbonate (BPTTC). Then P(St-b-BA-b-St) triblock copolymers were obtained through the RAFT block copolymerization of BA and PSt. At last, the triblock copolymers were reacted with equivalent 1,5-diazide pentane to provide (ABA)n type multiblock copolymers. The polymers were characterized by 1H NMR, IR and GPC measurements. The average number of repeating block DP n can reach 27 from the ratio of the number average molecular weights of the polymers before and after the coupling reaction.
