Abstract
"CONTROLE DE POLìMERO POR COCATALISADOR". Algumas propriedades tais como a resistência ao impacto de dardo, hexanos extraíveis e de pegajosidade da resina de um copolímero de polietileno produzido em uma polimerização em fase gasosa usando um catalisador de ZieglerNatta são mais bem controladas através do controle da relação de alumínio proveniente do co-catalisador em relação à taxa de produção do polímero. Isso possibilita aprimorar propriedades tais como a resistência ao impacto de dardo e reduzir os hexanos extraíveis mediante a alteração da quantidade de co-catalisador alimentado para dentro do reator.
