中文摘要 | poly (6-caprolactone) (pcl) and poly (l-lactide) (pla) were prepared by ring-opening polymerization catalyzed by organic amino calcium catalysts (ca/po and ca/eo) which were prepared by reacting calcium ammoniate ca(nh3)(6) with propylene oxide and ethylene oxide, respectively. the catalysts exhibited high activity and the ring-opening polymerization behaved a quasi-living characteristic. based on the fr-ir spectra and the calcium contents of the catalysts, and based on the h-1 nmr end-group analysis of the low molecular weight pcl prepared using catalysts ca/po and ca/eo, it was proposed that the catalysts have the structure of nh2-ca-o-ch(ch3)(2) and nh2-cao-ch2ch3 for ca/po and ca/eo, respectively. the ring-opening polymerization of cl and la follows a coordination-insertion mechanism and the active site is the ca-o bond. |
