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。
For improving the crystalline properties and hydrophilicity of the poly （β-hydroxybutyrate）, poly （ethylene glycol） /poly（β-hydroxybutyrate） dibloek copolymer was synthesized by the coupling reaction between hydroxyl-terminated poly（β-hydroxybutyrate） and acylate-terminated poly（ ethylene glycol） mon- omethyl ether. The dibloek copolymer was charaeterized by IR, ^1H NMR, X-ray analysis, DSC, and GPC. The result of water uptake suggested that the hydrophilieity of PHB was improved by the introduction of the MPEG segment.
