| 摘 要： | 采用新型化学酶法——开环易位聚合反应(ROMP)与酶促开环聚合反应(eROP)联用合成嵌段聚合物PCL-b-PB-b-PCL,用核磁共振氢谱(1 H NMR)、凝胶渗透色谱(GPC)和差示扫描量热法(DSC)表征产物的结构并进行性能测试.结果表明:GPC数据向高分子量移动,即成功合成了嵌段聚合物;嵌段聚合物可完全水解,且GPC数据向低分子量移动,表明该方法可行、有效.

| Abstract: | Copolymer PCL\|b\|PB\|b\|PCL was successfully prepared by a novel chemoenzymatic strategy coupled with enzymatic ring opening polymerization
(eROP) and ring opening metathesis polymerization (ROMP). The chemical structures of the products were characterized by 1H NMR, GPC and DSC. A complete shift of the GPC trace to higher molecular weightsillustrates that the copolymer was successfully prepared. 1H NMRdata clearly show block in the copolymer is hydrolyzed completely, and a clear shift of the GPC trace to lower molecular weightsillustrates that the synthetic strategy is reliability. |
