| 20110190512 | Method of Obtaining Lactide - The present invention relates to a method of obtaining lactide by means of a solvent of the ether class from a mixture that is in liquid form comprising lactide, meso-lactide, and other impurities. | 08-04-2011 |
| 20110155557 | Method for Obtaining Lactide - Processes for producing lactide from lactic acid oligomers are described herein. The processes generally include heating a lactic acid oligomer in the presence of a catalyst at a temperature of between 150° C. and 300° C. under a pressure of less than 0.01 MPa to form a lactide; distilling the lactide; and condensing and recovering the lactide, wherein the catalyst is a metal salt of the phosphite anion PO | 06-30-2011 |
| 20100113734 | PROCESS FOR PRODUCING POLYLACTIDE-URETHANE COPOLYMERS - A process for producing polylactide-urethane copolymers, which comprises the step of contacting a polylactide having terminal hydroxyl groups, produced by contacting at least one lactide monomer with a diol or diamine, with a diisocyanate compound optionally in the presence of a second diol or diamine in the presence of a catalytic system under polymerisation conditions characterised in that the polylactide and the polylactide-urethane copolymers are produced by reactive extrusion. | 05-06-2010 |
