Abstract

LA PRESENTE INVENCION PERMITE MEJORAR LA RESISTENCIA DE LA UNION ENTRE DISTINTAS CAPAS DE PELICULAS DE POLIPROPILENO, A TRAVES DE LA ADICION DE ETILENO COMO COMPOLIMERO MINI-ALEATORIO, EN CANTIDAD NO SUPERIOR A UN 1% EN PESO, Y MAS PREFERENTEMENTE NO SUPERIOR A ALREDEDOR DEL 0,7% EN PESO, Y AUN MAS PREFERENTEMENTE ENTRE UN 0,3% Y UN 0,5% EN PESO APROXIMADAMENTE, O INCLUSO CANTIDADES INFERIORES A UN 0,2% EN PESO. LA INVENCION PERMITE MEJORAR LA RESISTENCIA DE LA UNION INTERCAPAS EN PELICULAS DE CAPAS MULTIPLES, DANDO COMO RESULTADO ESPECIFICAMENTE UNA MEJOR RESISTENCIA DE LA JUNTA TERMICA. LA INVENCION ABARCA TANTO LAS PELICULAS RESULTANTES CON UNA MAYOR RESISTENCIA DE LA JUNTA TERMICA COMO EL PROCESO PARA LA PRODUCCION DE DICHAS PELICULAS. EN LA REALIZACION PREFERIDA, EL COPOLIMERO MINI-ALEATORIO PROPUESTO, SE FORMA EN UNA CAPA DE PELICULA USADA EN LUGAR DE UNA CAPA DE HOMOPOLIMERO DE PROPILENO, PROPORCIONANDO PROPIEDADES MEJORES DE UNION RESPECTO A UNA PELICULA FORMADA CON HOMOPOLIMERO DEPOLIPROPILENO, AL TIEMPO QUE MANTIENE A NIVELES ACEPTABLES LAS CARACTERISTICAS FISICAS Y OPTICAS DE UNA CAPA DE PELICULA REALIZADA CON UN HOMOPOLIMERO DE PROPILENO, COMO POR EJEMPLO LA RIGIDEZ.
