| 英文摘要 | Poly(d,l-lactide-co-p-dioxanone) (p(la-co-pdo)) copolymers with different chain microstructures were synthesized by one-step or two-step bulk ring-opening polymerizations of d,l-lactide (la) and p-dioxanone (pdo) monomers using stannous octoate [sn(oct)(2)]/n-dodecanol as the initiating system. the average sequence lengths of the lactidyl (l-la) and dioxanyl (l-pdo) units were calculated from the h-1 nmr spectra. it was found that both l-la and l-pdo values from the two-step syntheses were significantly longer than those from the corresponding one-step syntheses, indicating more blocky structure achieved for the two-step copolymers. corresponding to this difference in microstructure, the two-step copolymers were semi-crystalline, while the one-step copolymers were completely amorphous. in conclusion, the crystallinity of p(la-co-pdo) copolymers could be adjusted conveniently to meet specific applications by changing the microstructure of the copolymers via different polymerization routes.
