METHOD FOR MANUFACTURING POLYLACTIDE (PLA) USING A NEW POLYMERIZATION CATALYST. |
| abstract |
The invention relates to a method for manufacturing polylactide, which comprises the steps of mixing lactide and a metal coordination compound as a polymerization catalyst to obtain a reaction mixture, polymerizing the lactide in liquid phase at a temperature of at least 150 ° C to form liquid phase polylactide and allow the polylactide to solidify, characterized in that the polymerization catalyst comprises a metal ligand coordination compound with which the origin ligand responds to formula (I), with which R represents an atom of H, an aliphatic group, a halide atom or a nitro group and the metal is at least one of Zr and Hf; The invented catalyst shows the kinetics that is comparable with the kinetics of the known Sn octoate catalyst. |
