POLY LACTIC ACID MODIFIER, METHOD FOR PREPARING POLY LACTIC ACID MODIFIER, METHOD FOR MODIFYING POLY LACTIC ACID USING SAME, BIODEGRADABLE FOAM COMPOSITION USING MODIFIED POLY LACTIC ACID, AND FOAM FOR SHOES USING BIODEGRADABLE FOAM COMPOSITION

摘要

The present invention relates to a method for modifying a poly lactic acid and a biodegradable foam composition using the same. The method for modifying a poly lactic acid is characterized in that the poly lactic acid polymerizes to be modified into a molecule having a double bond, and the biodegradable foam composition is characterized by being produced through mixing and polymerization of the modified poly lactic acid and a mixing substance.
