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."CATALYST SYSTEM, PROCESS TO PREPARE A POLYOLEFINE, AND USE OF A CATALYST SYSTEM". The application concerns a catalyst system containing a metallocene, a co-catalyst, a support material and optionally, other organometallic compounds. The inventive catalyst system can be advantageous for the polymerization of olefins without using aluminoxanes, such as methylaluminoxane (MAO), which is usually used in considerable excess as a co-catalyst. A high level of catalyst activity and good polymeric morphology are guaranteed nonetheless. The catalyst activity can be significantly increased by adding hydrogen during the polymerization of olefins.
