Abstract

UNA COMPOSICION POLIMERA UTILIZABLE PARA LA PRODUCCION DE ARTICULOS DE MATERIAL PLASTICO BIODEGRADABLE, INCLUYE UN COPOLIMERO DE ETILENO/ALCOHOL DE VINILO Y ALMIDON DEGENERADO. PREFERIBLEMENTE, LA COMPOSICION SE OBTIENE POR MEZCLA DE COPOLIMERO DE ETILENO/ALCOHOL DE VINILO, EN UN ESTRUJADOR CALENTADO, CON UN COMPONENTE DE ALMIDON CONSTITUIDO POR UNA COMPOSICION DE ALMIDON DEGENERADO PRODUCIDO ANTES DE SU MANIPULACION MEDIANTE MEZCLA DE ALMIDON CON UN PLASTIFICADOR DE ALTO PUNTO DE EBULLICION, TAL COMO GLICERINA Y UN AGENTE DEGENERATIVO, CONSTITUIDO PREFERIBLEMENTE POR UREA, EN UN ESTRUJADOR. ALTERNATIVAMENTE, LA COMPOSICION PUEDE OBTENERSE POR MEZCLA DEL COPOLIMERO DE ETILENO/ALCOHOL DE VINILO CON ALMIDON Y UN PLASTIFICADOR EN UN ESTRUJADOR, CON AGUA A/ADIDA EN CANTIDAD NECESARIA Y POSIBLEMENTE CON UN AGENTE ADECUADO DE DESTRUCCION. LA COMPOSICION SE USA PARTICULARMENTE PARA LA PRODUCCION DE PELICULAS CON BUENA RESISTENCIA A LA PERFORACION Y ROTURA Y PARA ARTICULOS MOLDEADOS CON RESISTENCIA MECANICA MEJORADA. LOS PRODUCTOS HECHOS DE ESTA COMPOSICION SON TAMBIEN BUENAS BARRERAS DEFENSIVAS CONTRA EL OXIGENO Y EL DIOXIDO DE CARBONO.
