POLYMERIZATION OF MACROCYCLIC POLYESTER OLIGOMERS USING METAL AMIDE AND METAL ALKOXIDE CATALYSTS |
| 摘要 |
<p>Metal amide and metal alkoxide species have been found to catalyze the ring opening polymerization of macrocyclic polyester oligomers. The catalysts provide rapid polymerization, high monomer conversion, high molecular weight, and a mechanically sound material.</p> |
