| Abstract: | The catalytic activities of lanthanocene amides in ringopening polymerization of caprolactone have been investigated. Both the central metals and the ligands in amides showed effects on the catalytic activity. For the central metal, the activity increased with increase of ionic radii of the metal elements; for the amido groups, NC5H10 showed greater effect than N(iPr)2; for substituted cyclopentadienyl ligands, effect of tBuC5H4 was greater than that of MeC5H4. The mechanism of the ringopening polymerization has been briefly discussed. |
