Abstract

<B>PROCESSO PARA DESENCADEAMENTO DE POLIMERIZAçãO DE OLEFINA NA FASE GASOSA<D> O assunto da presente invenção é portanto processo para iniciar uma reação de polimerização de olefina de fase gasosa realizada utilizando um catalisador tipo Ziegler-Natta baseado em um metal de transição em um reator de base fluidizada, através do qual passa uma mistura de gases de reação compreendendo a olefina, um gás inerte, hidrogênio e, opcionalmente, pelo menos um comonómero e que opera sob condições de temperatura e pressão que tornam possível iniciar a reação de polimerização, caracterizado pelo fato de que a pressão parcial da olefina e a taxa de introdução do catalisador no reator são aumentadas enquanto mantendo as razões das pressões parciais entre a olefina e o hidrogênio e o comonómero ou comonómeros opcionais substancialmente constantes.
