Abstract

LA INVENCION ES RELATIVA A UNA POLIAMIDA BIODEGRADABLE. EN PARTICULAR, ESTA INVENCION ES RELATIVA A UNA POLIAMIDA CONTENIENDO GRUPOS QUETO CARBONILO FORMADOS EN UNIDADES MONOMERAS A LO LARGO DE LA CADENA PRINCIPAL DEL POLIMERO Y TENIENDO LA ESTRUCTURA EN DONDE N Y M SON NUMEROS TOTALMENTE IGUALES O DIFERENTES EN EL RANGO DE 8 A 10, PREFERIBLEMENTE 8. DICHAS POLIAMIDAS TIENEN ALTA SENSIBILIDAD A LA RADIACION SOLAR ULTRA VIOLETA, DE MODO QUE LA EXPOSICION DE LOS PRODUCTOS OBTENIDOS POR MEDIO DE TALES POLIAMIDAS A LA RADIACION SOLAR U.V. OCASIONA QUE LOS PRODUCTOS SEAN TRANSFORMADOS EN UN MATERIAL FRAGIL Y DESMENUZABLE, QUE ES BIODEGRADABLE.
