Polylactic acid block copolymers and preparation methods thereof
A polylactic acid triblock copolymer and a preparation method thereof are described. The polylactic acid triblock copolymer comprises an aromatic polyester oligomer block and a polylactic acid block. The polylactic acid triblock copolymer is obtained by reacting an aromatic polyester oligomer with a monomer lactide at a desired temperature. The polylactic acid block copolymer has a regular structure indicated by peak melting temperatures (Tm) corresponding to the aromatic polyester oligomer block and the polylactic acid block, respectively. Examples of the aromatic polyester oligomer block include polyethylene terephthalate, polybutylene terephthalate, and polyethylene 1,4-naphthalate. Examples of the monomer lactide include L-lactide and D-lactide.
