Abstract

SE PRESENTAN COMPOSICIONES PARA PELICULA MONOCAPA, IMPERMEABLE AL LIQUIDO, BIODEGRADABLE. EN PARTICULAR, LAS PELICULAS MONOCAPA COMPRENDEN ESTRUCTURAS COMPUESTAS DERIVADAS A PARTIR DE MEZCLAS DE POLIMEROS BIODEGRADABLES. LOS POLIMEROS BIODEGRADABLES SE SELECCIONAN A PARTIR DE CATEGORIAS DE POLIMEROS SENSIBLES A LA HUMEDAD, POLIMEROS TERMICAMENTE SENSIBLES, POLIMEROS MECANICAMENTE LIMITADOS, POLIMEROS NO FACILMENTE PROCESADOS EN PELICULAS, POLIMEROS HIDROLITICAMENTE DIVISIBLES Y ELASTOMEROS DEGRADABLES. LOS POLIMEROS BIODEGRADABLES SE COMBINAN EN DIFERENTES FORMAS PARA SOSLAYAR LAS DIFERENCIAS DE LOS COMPONENTES INDIVIDUALES, IMPARTIENDO AL MISMO TIEMPO PROPIEDADES DE CARACTERISTICAS ESPECIFICAS A LA PELICULA. LAS COMPOSICIONES PARA PELICULA MONOCAPA SON ADECUADAS PARA SU USO COMO LAMINAS DE RESPALDO EN PRODUCTOS ABSORBENTES DESECHABLES INCLUYENDO COMPRESAS, PAÑALES PARA LA INCONTINENCIA DE ADULTOS, SALVASLIPS, Y SIMILARES.
