Abstract

LA FLUIDEZ A BAJAS TEMPERATURAS DE COMPUESTOS BASADOS EN HIDROCARBUROS LIQUIDOS DE REFINO SON MEJORADOS POR MEDIO DE LA ADICION, PREFERIBLEMENTE EN FORMA DE SOLUCION, DE COPOLIMEROS DE ETILENO/PROPILENO/(DIENO CONJUGADOS) O TERMOPOLIMEROS, CONTENIENDO 20-55% DE PROPILENO, OPCIONALMENTE REBAJADO POR TERMO-OXIDACION, Y CARACTERIZADO ESTRUCTURALMENTE POR VALORES DE AL MENOS UN PARAMETRO DE X2 Y X4, LOS CUALES SERAN IGUAL O MENOR QUE 0,02 APROXIMADAMENTE, INDICATIVO DE LA AUSENCIA EN LA CADENA POLIMERICA DE MUTACIONES EN EL ENCADENAMIENTO DEL PROPILENO.
