| Abstract: | A novel kind of copolymers was synthesized by ring opening copolymerization of glycolide and 2 hydro 2 oxo 1,3,2 dioxaphosphorinane,using triisobutylaluminium as the initiator. Their structures were confirmed by 1H NMR and FTIR. The influence of molar ratio of monomers and time on the total conversion, copolymer composition and molecular weight were investigated, respectively. The crystallinity degree and cell dimensions of the copolymers were determined by XRD. |
