- •A process for chemical recycling of PLA by alcoholysis is developed for circular economy.
- •Standard quantitative analysis techniques are developed by FTIR, 2D-NMR and 1H-NMR.
- •Reactivity of different alcohols toward the alcoholysis reactions is investigated.
- •The alcoholyzed PLA products are used as starting materials for PLA-based polyurethanes.
- •The PU materials exhibit excellent mechanical properties, with healing property.
