Abstract

Se describen composiciones polimetricas capaces de formar micelas estables en una solucion acuosa, que comprenden un copolimero de bloque anfifilico de un bloque hidrofilito, y un derivado de acido poli lactico en donde un extremo del acido polilactico se enlaza covalentemente a por lo menos un grupo carboxilo. El grupo carboxilo del derivado de acido polilactico puede fijarse con un iòn de metal di o trivalente, obtenido mediante la adicion del iòn de metal di o trivalente a la composicion polimerica.
