Polymerization of macrocyclic polyester oligomers at elevated temperature using rare earth element catalysts |
| abstract |
Compounds containing a lanthanide rare earth element or yttrium are effective catalysts for the polymerization of macrocyclic polyester oligomers. The catalysts are stable at elevated temperatures, and the polymerization is rapid, resulting in high monomer conversion, high molecular weight, and a mechanically sound material. |
