Abstract

"CONTROLE DE GOTìCULAS DE CATALISADOR EM SOLUçãO". A presente invenção refere-se a um processo, realizado em fase gasosa, compreendendo contatar uma ou mais olefinas com um sistema catalisador contendo um gás portador e uma mistura de sólidos compreendendo um composto ou complexo de metal de transição e um solvente orgânico líquido, sob condições de polimerização, em um reator de leito fluidizado contendo partículas de resina em um estado fluidizado com as ressalvas de que: (a) a mistura de sólidos e solvente contém pelo menos 95 por cento em peso de sólidos, e (b) a mistura é aspergida com o gás portador dentro de uma zona pobre em partículas, ou o leito fluidizado, do reator.
