Synthesis and Properties of Cellulose Diacetate graft Poly(p-dioxanone) Copolymers Via the Couple-Grafting Copolymerization

摘要：

　　A new biodegradable copolymer of cellulose diacetate and poly(p-dioxanone) (PPDO) was prepared through a couple-grafting procedure.PPDO was functionalized with the isocyanate group,and then PPDO terminated with the isocyanate group was enabled to react with the hydroxyl groups of cellulose diacetate.The length of PPDO graft chains can be controlled easily by using the prepolymers of PPDO with different molecular weights.The resulting products were thoroughly characterized with FT-IR,1H-NMR.The mechanical properties of the copolymers were affected greatly by the length of PPDO segment.
