Abstract

UNA PELICULA DE PERMEABILIDAD CONTROLADA QUE INCLUYE UNA PELICULA QUE FORMA POLIMEROS Y QUE OPCIONALMENTE INCLUYE UN POLIMERO DISPERSANTE; Y UN FILTRO POROSO INERTE QUE OPCIONALMENTE TIENE UN AGENTE MODIFICADOR DE SUPERFICIE QUE LE CUBRE, ESTANDO PRESENTE EL FILTRO POROSO INERTE EN UNA CANTIDAD EFECTIVA PARA REDUCIR LA RELACION ENTRE LA PERMEABILIDAD AL DIOXIDO DE CARBONO Y LA PERMEABILIDAD AL OXIGENO DE LA PELICULA, Y DONDE EL FILTRO TIENE UN TAMAÑO DE PARTICULA MAYOR QUE EL ESPESOR INTRINSECO DE LA PELICULA QUE FORMA POLIMEROS. TAMBIEN SE DESCUBRE UN ARTICULO ENCAPSULANTE COMPUESTO Y UN PRODUCTO DE PRODUCCION ENCAPSULADO.
