Oxygen Polylactic acid

Anionic polymerization proceeds by nucleophilic reaction of the anion with the carbonyl and the subsequent acyl-oxygen cleavage. This reaction produces an alkoxide end group, which continuously propagate to prepare polylactic acid (Figure 7.5) [12]. 

Lactic acid has been used in the food, chemical and pharmaceutical industries for years, and has the potential to achieve commodity-level status as an intermediate for oxygenated chemicals, "green" solvents, specialty chemical intermediates, and polylactic acid (PLA). PLA, which is already used in medical devices, holds great promise for increased use as a versatile, environmentally-...
