Bio-based synthetic polyesters PLA and alkanoates Polylactic fibres PLA William Carothers pioneered the production of an aliphatic polyester from lactic acid in 1932, however, the resulting polymer had poor mechanical properties and a low molecular weight. In 1954, DuPont in USA developed and patented a higher molecular weight polymer of this polyester. This type of
