| 中文摘要 | a novel rare earth coordination system composed of lanthanide trifluoroacetates ln(cf3coo)(3) (ln = y, yb, nd, tm, ho, la, pr) and triisobutylaluminium al(i-bu)(3) was used as catalyst for the polymerization of epsilon-caprolactone (cl), d,l-lactide (dlla) and their copolymerization. the influence of temperature, time and catalyst concentration on polymerization yields and molecular weights of the polyesters have been studied. it was shown that the ring-opening polymerization of cyclic esters catalysed by ln(cf3coo)(3)/al(i-bu)(3) has some living character and the molecular weight of the polyester could be controlled by adjusting the molar ratio of monomer to catalyst. the dlla/cl copolymer was synthesized by sequential addition of monomers and the structure of the copolyester was characterized by gpc, nmr and dsc.
