摘    要:为改进聚(β-羟基丁酸酯)(PHB)的结晶性和亲水性,通过聚乙二醇单甲醚(MPEG)的端酰氯基团和聚(β-羟基丁酸酯)的端羟基基团的官能团反应,制备了聚乙二醇/聚(β-羟基丁酸酯)两嵌段共聚物。通过红外光谱、核磁、X射线衍射、差热分析和凝胶渗透色谱等手段,证明制备了嵌段共聚物。吸水实验表明,材料的亲水性得到了明显的改善。

关 键 词:聚乙二醇  聚(β-羟基丁酸酯)  共聚物

Abstract:For improving the crystalline properties and hydrophilicity of the poly(β-hydroxybutyrate),poly(ethylene glycol) /poly(β-hydroxybutyrate) diblock copolymer was synthesized by the coupling reaction between hydroxyl-terminated poly(β-hydroxybutyrate) and acylate-terminated poly(ethylene glycol) monomethyl ether.The diblock copolymer was characterized by IR,1H NMR,X-ray analysis,DSC,and GPC.The result of water uptake suggested that the hydrophilicity of PHB was improved by the introduction of the MPEG segment.
Keywords:poly(ethylene glycol)  poly(β-hydroxybutyrate)  copolymer
