Abstract

métodos para preparar produtos de poliolefinas tendo propriedades de afinamento por cisalhamento e névoa diferentes. a invenção refere-se a um método para preparar uma poliolefina compreendendo contatar uma ou mais olefinas, em um reator contendo um catalisador; polimerizar as uma ou mais olefinas para produzir um polímero de olefina caracterizado por uma primeira razão de fluidez (mfr) e uma primeira névoa; e alterar a temperatura de reação no reator para alterar a primeira mfr para uma mfr que é diferente da primeira mfr e para alterar a primeira névoa para uma névoa que é diferente da primeira névoa.
