Abstract
PROCEDIMIENTO DE OBTENCION DE POLIETILENO. CONSISTE EN FUNDIR DE UN 50 A 98 POR CIEN EN PESO DE POLIETILENO DE ALTA DENSIDAD, SUPERIOR O IGUAL A 0,940 CON UN 2 A 50 POR CIEN EN PESO DE POLIETILENO DE BAJA DENSIDAD LINEAL INFERIOR A 0,930. EL AMASADO TIENE LUGAR EN ESTADO FUNDIDO A PARTIR DE LA MEZCLA DE POLVOS O DE GRANULADOS DE LOS CONSTITUYENTES DIRECTAMENTE EN LAS MAQUINAS DE TRANSFORMACION EN OBJETOS TERMINADOS TALES COMO EXTRUSORAS. LA POLIMERIZACION TIENELUGAR BAJO PRESION INFERIOR A 4.10 ELEVADO 6 PA EN PRESENCIA DE UN CATALIZADOR QUE COMPRENDE UN COMPUESTO DE METAL DE TRANSICION DE LOS SUB-GRUPOS IVA, VA Y VIA. EL POLIETILENO DE BAJA DENSIDAD SE OBTIENE POR COPOLIMERIZACION EN FASE GASEOSA PRINCIPALMENTE EN LECHO FLUIDIZADO.
