Abstract

Esta divulgación se relaciona con un proceso de polimerización en solución continuo en tres reactores. El solvente del proceso, etileno, comonómeros opcionales, hidrógeno opcional y un sistema catalizador de sitio único se inyectan en un primer y un segundo reactores configurados en paralelo entre sí. Un tercer reactor recibe el efluente del primer reactor, del segundo reactor o una combinación del primer y segundo reactores. Se alimenta el monómeros frescos al tercer reactor para una polimerización y para obtener un producto de polietileno final.
