Producers have several industrial routes to usable (i.e. high molecular weight) PLA. Two main monomers are used: lactic acid, and the cyclic di-ester, lactide. The most common route to PLA is the ring-opening polymerization of lactide with various metalcatalysts (typically tin octoate) in solution. Another route to PLA is the direct condensation of lactic acid monomers. This process needs to be carried out at less than 200 °C;above that temperature, the entropically favored lactide monomer is generated.
