摘要 结合原子转移自由基活性聚合(ATRP)和点击化学中铜催化的炔基/叠氮偶极环加成(CuAAC)反应,可控合成两亲性环状聚(己内酯-b-乙烯基吡咯烷酮)嵌段共聚物(Cyclic-PCL-b-PVP),通过傅里叶变换红外光谱(FT-IR)、核磁共振氢谱(1H-NMR)和凝胶渗透色谱(GPC)分别表征聚合物的结构、分子量及分子量分布,表明已成功合成两亲性环状聚(己内酯-b-乙烯基吡咯烷酮)。采用热重分析(TGA)和接触角测量研究了两亲性共聚物的热力学性能和亲水性能,结果表明,相比于线形聚(己内酯-b-乙烯基吡咯烷酮)(Linear-PCL-b-PVP),相应的环状嵌段共聚物的热稳定性明显提高,亲水性亦有所变化。

Abstract: The amphiphilic cyclic-poly(ε-caprolactone)-b-poly(N-vinylpyrrolidone) copolymer (cyclic-PCL-b-PVP) was synthesized via atom transfer radical polymerization (ATRP) and click chemistry. The structure, molecular weight and molecular weight distribution of the copolymer were characterized by FT-IR, 1H-NMR, GPC respectively. The thermodynamic properties and the hydrophilicity of the copolymer were studied by TGA and contact angle measurement. Our results indicated an evidently higher thermal stability and a different hydrophilicity of the cyclic copolymer compared with linear-PCL-b-PVP.
