发明名称 MANUFACTURING METHOD OF COLORED POLYLACTIC ACID RESIN
摘要 PURPOSE: A manufacturing method of colored polylactic acid is provided to effectively manufacture a polylactic acid resin with various colors in short time by using a selective initiator which determines the color. CONSTITUTION: A manufacturing method of colored polylactic acid comprises: a step of synthesizing an aluminum catalyst ligand in a solvent; and a step of adding a lactide monomer and a selective initiator determining the color into the solvent with the aluminum catalyst ligand, and conducting a polylactic acid polymerization. The solvent is selected from toluene, benzene, pentane, cyclopentane, hexane, cyclohexane, chloroform, diethyl ether, or 1,4-dioxane. The aluminum catalyst ligand is obtained by mixing trimethylaluminum and a C5H4N(CO)NHC6H4(NO2)2 solution.
