Abstract

Es un objetivo de la presente invención proporcionar un proceso o método para producir un copolímero en bloque de ácido poliláctico que tiene alto peso molecular y es bajo en costo, en donde solamente un cristal estereo-complejo puede crecer, aun cuando el proceso de fusión de calor se repite. La presente invención se refiere a un proceso o método para producir un copolímero en bloque de ácido poliláctico caracterizado porque (i) la polimerización de apertura de anillo del D-lactida-(Componente D) se lleva a cabo en la presencia de ácido poli-L-láctico (Componente L), o (ii) la polimerización de apertura de anillo del L-lactida (Componente L) se lleva a cabo en la presencia de ácido poli-D-láctico (Componente D) y la relación de masa del Componente D y el componente L es el componente D/el componente L = 60/40 hasta 91/9, o el componente L/el componente D = 60/40 hasta 91/9.
