摘要：

Biodegradable polymers in bio-based and chemically synthesized polymers are good substitutes to reduce non-degradable massive waste plastics. Biodegradable and CO2-redcible polylactides are widely used in commercial fields. The biodegradability is one of the most important factors affecting their wide applications. The objective of this study was to investigate hydrolytic kinetics of enantiomeric polylactide mixture monolayers with different molecular weights using a Langmuir film balance. The pi-A and kinetic behaviors of mixture monolayers were compared with each other to determine the stereocomplexation effect between enantiomeric polylactides as a function of molecular weight.
