Abstract

Abstract: Biodegradable polymer blends based on polylactide (PLA) were reviewed, including blends of enantiomeric polylactides, PLA/ aliphatic polyester, PLA/ natural polymers, PLA/ poly(ε-caprolactone), PLA/ poly (ethylene glycol), PLA/ poly(vinyl alcohol), and PLA/ poly(vinylpyrrolidone). Current research showed that with addition of other biodegradable polymers to PLA, the mechanical properties and flexibility could be improved, and the cost was lowered. The blends hold environmentally friendly characteristic and enlarge the application field of PLA materials in engineering plastics and packaging.

Key words: polylactide, biodegradability, blend
