| 英文摘要 | A series of lutetium alkyl, amino, and guanidinato complexes based upon an amino-phosphine ligand framework had been prepared. these complexes were applied to initiate ring-opening polymerization of 2,2'-dimethyltrimethylene carbonate (dtc). the type of the initiator significantly influenced the catalytic activity of these complexes in a trend as follows: alkyl approximate to guanidinate > amide, whereas the complexes with flexible backbone between p and n atoms within the ligand exhibited higher activity than those with rigid backbone. the isolated pdtc had bimodal-mode molecular weight distribution. the molecular weights of each fraction increased linearly with the conversion, indicating that there might be two active species. this had been confirmed by analyses of oligomeric dtc living species and oligomer with nmr technique as the metal-alkoxide and the four-membered metallocyclic lactate. kinetic investigation displayed that the polymerization rate was the first order with the monomer concentration.
