摘要:
The present invention relates to a polysiloxane-polylactide block copolymer and a preparation method thereof, in which the polysiloxane-polylactide block copolymer has improved impact resistance and flexibility, compared to the conventional polylactide resins and can be prepared by ring-opening polymerization of lactide monomers in the presence of a polymerization initiator of polysiloxane.
摘要:
Disclosed are polylactide resin that may exhibit and maintain excellent mechanical properties, exhibit excellent heat resistance, and thus can be used for a semi-permanent use, a method for preparing the same, and a polylactide resin composition comprising the same.The polylactide resin has a low hydrolysis rate constant of 0.1 day−1 or less and a weight average molecular weight of 100,000˜1,000,000, under specific conditions.
