Abstract

METODO DE FABRICACION DE PELICULAS ESTIRADAS DE CAPAS MULTIPLES DE POLIPROPILENO CON BUENAS PROPIEDADES OPTICAS Y SOLDABILIDAD TERMICA. LA PELICULA SE OBTIENE ESTRATIFICANDO UNA CAPA DE UNA COMPOSICION (B) QUE CONTIENE UN HOMOPOLIMERO O COPOLIMERO DE ETILENO, PROPILENO O 1-BUTENO Y UN POLIMERO DE VINILCICLOALCANO (POLIMERO A), SOBRE, AL MENOS, UNA CAPA DE POLIPROPILENO CRISTALINO ESTIRADO. EL VINILCICLOALCANO PUEDE SER VINILCICLOPENTANO, VINILCICLOHEXANO O VINILNORBORNADO U OTROS; EL POLIMERO A ES UN HOMOPOLIMERO O COPOLIMERO DE DICHO VINILCICLOALCANO. EL POLIPROPILENO CRISTALINO Y LA COMPOSICIO B SE EXTRUYEN Y ESTRATIFICAN CONJUNTAMENTE Y LUEGO SE APLICA UN ESTIRAJE MONOAXIAL O BIAXIAL SUCESIVO O SIMULTANEO; TAMBIEN SE PUEDE EXTRUIR EL POLIPROPILENO CRISTALINO, ESTIRARLO MONOAXIALMENTE Y ESTRATIFICARLO CON LA COMPOSICION B Y TAMBIEN SE PUEDE PROCEDER ESTIRANDO EL POLIPROPILENO EXTRUIDO MONO Y BIAXIALMENTE Y LUEGO ESTRATIFICARLO CON LA COMPOSICION B.
