可逆加成-断裂链转移自由基聚合反应制备含氟丙烯酸酯嵌段共聚物
Keywords: 含氟丙烯酸,dbttc,可逆加成-断裂链转移反应(raft)
Abstract:
？以苯乙烯（st）、1h,1h,2h,2h-丙烯酸全氟癸酯（foa）为聚合单体，二苄基三硫代碳酸酯（dbttc）作为raft试剂，通过可逆加成-断裂链转移反应合成了一系列ps-pfoa-ps三嵌段含氟共聚物。傅里叶红外测试（ft-ir）表征了产物的结构，gpc、核磁等测试结果证明聚合过程符合活性聚合机理，聚合产物相对分子质量及其分布可控。dsc、xrd测试结果验证了聚合产物具有结晶性质，同样研究了测试溶剂对于含氟共聚物核磁结果的影响。
