Synthesis of star poly (L-lactic acid) and its copolymers catalyzed by lipase in supercritical carbon dioxide

Poly (L-lactic acid) (PLLA) is a bio-based biodegradable polymer with minimal immunogenicity, non-toxicity and excellent mechanical properties and has widely used in medical, pharmaceutical, food packaging and other fields. However, linear PLLA has the characteristics of high melting point, strong c...
