摘要 研究了浓硫酸催化聚(β-羟基丁酸酯)在氯仿溶剂中的降解反应,使用凝胶渗透色谱(GPC)、核磁共振(1H-NMR)、红外光谱(IR)和X-射线衍射(XRD)等手段对产物结构进行了表征。结果表明:降解产物为一端带有羟基的PHB遥爪聚合物,结构与PHB原料结构一致。 The degrading process of Poly（β-hydroxybutyrate） using concentrated sulfuric acid as catalyst in chloroform was studied. The structure of the products was characterized by GPC, ZHNMR, IR and XRD. The results showed that the product is telechelic polymer with hydroxyl. The structure of the degrading product is similar to the structure of Poly （β-hydroxybutyrate）.
