ACETYLATED LACTIDE OLIGOMER-BASED PLASTICIZER AND THE METHOD OF MANUFACTURING THE SAME, PLA RESIN COMPOSITION COMPRISING ACETYLATED LACTIDE OLIGOMER-BASED PLASTICIZER

摘要

It is an object of the present invention to provide an acetylated lactide oligomer-based plasticizer having improved thermal stability, excellent plasticization performance, and excellent compatibility with a resin, and a method for preparing the same. The present invention provides the steps of: (a) synthesizing a lactide oligomer by ring-opening polymerization (ROP) of an initiator and lactide; (b) performing an acetylation reaction by adding acetic anhydride to the lactide oligomer; and (c) removing acetic acid and unreacted acetic anhydride produced in step (b).
