Abstract

Método para controlar o fluxo de polímero num processo de polimerização. O presente invento descreve um método para controlar a fluidez de partículas poliméricas fluído para baixo numa forma densificada dentro de um reator de polimerização, em que um ou mais monómeros são polimerizados em fase gasosa na presença de um catalisador de polimerização, a densidade do sólido (kg de polímero por m¬ 3¬ de reator ocupado pelo polímero) sendo maior que 80% da "densidade aparente" do polímero, o método sendo caracterizado pelo fato que uma corrente líquida é continuamente alimentada ao reator de polimerização a uma taxa de fluxo de massa por unidade de superfície do reator maior que 30 kg/h m¬ 2¬.
