What is it about?
Prepearation of PLA from lactic acid condensation was catalyzed by acidic montmorillonite K-10 clay. This clay obviously promoted the polymer's molecular weight like as metal catalysts.

Why is it important?
This metal-free catalytic synthesis is importantant because ; End-product doesn't have any metal residuals so no need any post-process for removing the ctalyst.
