Abstract

La presente invención se refiere a partículas estables de láctido, más específicamente a partículas de láctido que son lo suficientemente estables para ser almacenadas y transportadas a temperatura ambiente, y tienen una calidad lo suficientemente alta para usarlas como material de partida para el ácido poliláctico; la partícula de láctido tiene una relación de superficie/volumen de menos de 3000 m-1, de preferencia el láctido en la partícula tiene una pureza óptica de por lo menos el 95%; las partículas de láctido se preparan sometiendo el láctido a un paso de configuración que comprende extrusión, formación de pastillas, granulación, formación de tabletas o formación de hojuelas.
