Method of making polylactic acid and its products |
| abstract |
The present disclosure provides a method for preparing polylactic acid and its products using a twin-screw extruder, comprising the step of mixing carbon dioxide adducts of carbene and lactide, and obtaining polylactic acid and its products via reactive extrusion using a twin-screw extruder. Some of the carbon dioxide adducts or carbene have the following general formula: |
