Abstract
La presente invencion se refiere a polímeros biodegradables y en especial polímeros biodegradables a base de ácido poliacrílico y/o poliaspártico. Por otra parte, la presente invencion se refiere a métodos para la preparacion de los presentes polímeros biodegradables y su uso como, por ejemplo, capa protectora o material de empaque. Específicamente, la presente invencion se refiere a métodos para preparar un polímero biodegradable que comprende: a) preparar una mezcla ácida de ácido poliacrílico y/o poliaspártico, iones sodio, uno o varios oligosacáridos o sus derivados y agua, en donde la mezcla resultante tiene un pH igual o menor que 5; b) mantener la temperatura de dicha mezcla ácida en un rango de 80°C a 130°C hasta obtener una suspension homogénea; y c) anadir alcohol polivinílico (PVA) y uno o varios ácidos policarboxílicos o sus derivados, a la mezcla de la etapa (b) mientras se mantiene la temperatura en un rango de 80 °C a 130 °C hasta formar el polímero biodegradable.
