| 中文摘要 | divalent samarocene complex [(c5h9c5h4)(2)sm(tetrahydrofuran)(2)] was prepared and characterized and used to catalyze the ring-opening polymerization of l-lactide (l-la) and copolymerization of l-la with caprolactone (cl). several factors affecting monomer conversion and molecular weight of polymer, such as polymerization time, temperature, monomer/catalyst ratio, and solvent, were examined. the results indicated that polymerization was rapid, with monomer conversions reaching 100% within 1 h, and the conformation of l-la was retained. the structure of the block copolymer of cl/l-la was characterized by nmr and differential scanning calorimetry. the morphological changes during crystallization of poly(caprolactone) (pcl)-b-p(l-la) copolymer were monitored with real-time hot-stage atomic force microscopy (afm). the effect of temperature on the morphological change and crystallization behavior of pcl-b-p(l-la) copolymer was demonstrated through afm observation. |
