Process for production of polylactic acid |
| abstract |
PROBLEM n There is provided a method for producing polylactic acid, which is capable of obtaining polylactic acid at low cost, and having high molecular weight. n SOLUTION n A method for producing polylactic acid by polymerizing molten lactide using at least one reactor having plug flow characteristics with ξ (τ), calculated from the following FORMULA (1), of 0.3 or smaller: ξ τ = ∫ 0 ∞ E τ × ABS 1 - τ d τ in the Formula (1), E (τ) is a residence time distribution function determined by impulse response by starch syrup having a viscosity of 3 Pa•s, and τ is ratio of elapsed time θ and mean residence time θ 0 . |
