Polylactic acid or polylactide (PLA)

pla chemical formula

Polylactic acid or polylactide (PLA) is a thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States), tapioca roots, chips or starch (mostly in Asia), or sugarcane (in the rest of the world). In 2010, PLA was the second most important bioplastic of the world in regard to consumption volume. The name “poly(lactic acid)” does not comply with IUPAC standard nomenclature, and is potentially ambiguous or confusing, because PLA is not a polyacid (polyelectrolyte), but rather a polyester.

According to the International Union of Pure and Applied Chemistry (IUPAC Standard), the name polyactic acid is not compliant to their nomenclature as PLA is not a polyacid but rather a polyester.
