Abstract

PROCEDIMIENTO PARA LA PREPARACION DE UNA COMPOSICION DE POLIETILENO EXTRUIBLE Y RECTIFICABLE.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE PREPARA UNA COMPOSICION FORMADA POR UNA POLIOLEFINA CONSTITUIDA POR UN POLIETILENO O POR UN COPOLIMERO DERIVADO DEL ETILENO Y POR UNA OLEFINA C3 A C8, POR UN ADITIVO REACTIVO DE TRANSFORMACION CONSISTENTE EN UN POLIMERO DE ACRILATO DE N-ALQUILO C14 A C24, Y POR UN COMPUESTO GENERADOR DE RADICALES LIBRES, EN UNA PROPORCION MINORITARIA; SEGUNDA, LA COMPOSICION FORMADA SE SOMETE A UN PROCESO DE EXTRUSION,QUE SE REALIZA A UNA TEMPERATURA INFERIOR A LA TEMPERATURA DE DESCOMPOSICION DEL COMPUESTO GENERADOR DE RADICALES LIBRES; Y POR ULTIMO, SE RETICULA EL PRODUCTO EXTRUIDO A UNA TEMPERATURA QUE PERMITA LA DESCOMPOSICION DEL COMPUESTO GENERADOR DE RADICALES LIBRES.
