Abstract

MEZCLAS DE POLIMEROS DE POLIPROPILENO ISOTACTICO Y POLIPROPILENO SINDIOTACTICO AUMENTAN LA FACILIDAD DE MANEJO EN LAS APLICACIONES DE PELICULAS. HASTA UN NIVEL DE 4% EN PESO DE POLIPROPILENO SINDIOTACTICO SE INCREMENTARA LA DISTRIBUCION DE PESO MOLECULAR.SE MEJORA HASTA UN NIVEL DE 13.9% EN PESO DE POLIPROPILENO SINDIOTACTICO LA CLARIDAD O NEBLINA DE LA PELICULA ORIENTADA BIAXIALMENTE. DENTRO DE UN RANGO DE APROX. 2.34% EN PESO DE POLIPROPILENO SINDIOTACTICO HASTA APROX. UN 13.9% EN PESO EL FLUJO DE FUSION ES SUPERIOR AL DE UN HOMOPOLIMERO SINDIOTACTICO, O AL DE UN HOMOPOLIMERO ISOTACTICO.DENTRO DE UN RANGO DE APROX. UN 2% EN PESO DE POLIPROPILENO SINDIOTACTICO HASTA APROX. UN 13.9% EN PESO, EL NIVEL DE SOLUBLES DE XILENO ES SUPERIOR AL DE UN HOMOPOLIMERO SINDIOTACTICO O AL DE UN HOMOPOLIMERO ISOTACTICO.SI SE SELECCIONAN CATALIZADORES APROPIADOS, PUEDE SER PRODUCIDA DE LA MEZCLA DESEADA.
