Abstract

PROCESSO PARA POLIMERIZAR POLÍMEROS À BASE DE ETILENO. A divulgação é direcionada a um processo para polimerizar polímeros à base de etileno. O processo inclui polimerizar etileno e, opcionalmente, um ou mais monômeros de (C3-C14)a-olefina, e pelo menos um dieno, na presença de pelo menos um catalisador de múltiplas cadeias e pelo menos um catalisador de cadeia única. O processo pode incluir um solvente. O catalisador de múltiplas cadeias no processo inclui uma pluralidade de sítios de polimerização. Os polímeros ramificados de cadeia longa são sintetizados conectando-se as duas cadeias de polímero do catalisador de múltiplas cadeias com o dieno, a junção das duas cadeias de polímero sendo realizada em uma maneira concertada durante a polimerização. Os polímeros à base de etileno são produzidos e incluem pelo menos duas frações de polímero de peso molecular. O catalisador de múltiplas cadeias produz a fração de alto peso molecular, que é o polímero ramificado de cadeia longa.
