Abstract

"PROCESSO PARA A POLIMERIZAçãO DE ETILENO E OPCIONALMENTE PELO MENOS UM COMONÈMERO DE ALFA OLEFINA, USO DE PELO MENOS DUAS CORRENTES DE ALIMENTAçãO, E, REATOR DE POLIMERIZAçãO EM SUSPENSãO". Um processo para a polimerização de etileno e opcionalmente pelo menos um comonómero de alfa olefina C~ 3-20~ na fase de suspensão ou solução em um reator tendo uma corrente de saída de polímero, uma corrente de alimentação de pró-catalisador ou catalisador e uma corrente de alimentação de hidrogênio, dita polimerização sendo efetuada na presença de um catalisador de metaloceno, um diluente e hidrogênio, em que dito diluente é reciclado a partir de dita acorrente de saída para dita corrente de alimentação de hidrogênio, dita corrente de alimentação de pró-catalisador ou catalisador é livre de hidrogênio, dita corrente de alimentação de hidrogênio é livre de pró-catalisador ou catalisador e dita corrente de alimentação de prócatalisador ou catalisador não compreende diluente reciclado.
