| Summary: | Заглавие с титульного экрана This study presents methods of analytical control of the production of polylactic acid. This processincludes next stages: concentrating and oligomerization of lactic acid, depolymerization of the lactic acidoligomer and lactide polymerization. The important criterion is the purity of the monomer which is obtained atthe stage of depolymerization. The monomer purity was assessed titrimetric methods and by UV-spectroscopy.These methods make it possible to determine the lactic acid concentration at the level of 10-6 - 10-3 g / ml. |
