Abstract
"SISTEMA DE CATALISADOR, PROCESSO PARA PREPARAR UMA POLIOLEFINA,E, USO DE UM SISTEMA DE CATALISADOR". O pedido diz respeito a um sistema de catalisador que contenha um metaloceno, um co-catalisador, um material de suporte e opcionalmente, outros compostos organometálicos. O sistema inventivo de catalisador pode ser vantajoso para a polimerização de olefinas sem usar aluminoxanos, tais como metilaluminoxano (MAO), que é usualmente usado em excesso considerável como um co-catalisador. Um alto nível da atividade de catalisador e boa morfologia polimérica são garantidas apesar de tudo. A atividade de catalisador pode ser significantemente aumentada pela adição de hidrogênio durante a polimerização das olefinas.
