Abstract

UNA COMPOSICION QUE CONSTA DE UN POLIMERO POLILACTIDO CON UNA VISCOSIDAD EXTENSIONAL MEJORADA Y METODOS PARA PRODUCIRLO. LA COMPOSICION DE POLIMERO POLILACTIDO SE PREPARA PROPORCIONANDO EN LA MISMA MOLECULAS DE POLIMERO POLILACTIDO QUE HAN SIDO MODIFICADAS, RELATIVAS A UN POLILACTIDO NO SUSTITUIDO LINEAL, PARA PROPORCIONAR UNA INTERACCION MOLECULAR INCREMENTADA ENTRE LAS CADENAS PRINCIPALES DE POLILACTIDOS EN LA COMPOSICION. LA COMPOSICION DE POLIMERO POLILACTIDO PREFERIDA TIENE UN PESO MOLECULAR MEDIO DE AL MENOS APROXIMADAMENTE 10000 (PREFERIBLEMENTE AL MENOS 50000) Y UNA POLIDISPERSIDAD DE AL MENOS APROXIMADAMENTE 2.5. ADEMAS, LA COMPOSICION DE POLIMERO POLILACTIDO DEBERIA TENER UN INDICE DE NECK-IN INFERIOR A ALREDEDOR DE 0.8.
