Polylactic Acid Complex and Production Method Thereof

摘要

This method comprises a primary cross-linking step wherein cross-linked polylactic acid is formed by cross-linking a polylactic acid molded product; an impregnation step wherein the cross-linked polylactic acid obtained in the primary cross-linking step is immersed in an impregnant at a temperature that is not lower than the glass transition temperature of polylactic acid and not higher than the melting point of polylactic acid; and a cooling step wherein the cross-linked polylactic acid, which is in the swollen state because of the impregnation of the impregnant, is cooled to temperatures equal to or lower than the glass transition temperature of polylactic acid. This method may further comprise a secondary cross-linking step following the cooling step.
