Abstract
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.
