Abstract

MéTODOS PARA PRODUçãO DE POLìMEROS COM CONTROLE SOBRE A DISTRIBUIçãO DA COMPOSIçãO. Os métodos para controlar a viscosidade de fusão de uma poliolefina, através do controle da distribuição de comonómeros de uma poliolefina, que alcança a viscosidade de fusão almejada de uma poliolefina, e películas feitas de tais poliolefinas são fornecidos. Os métodos incluem contato de um monómero de olefina e pelo menos um comonómero com um sistema de catalisador na presença de um fluido condensável, compreendendo um hidrocarbono saturado tendo de 2 a 8 átomos de carbono. O sistema de catalisador em uma modalidade inclui um componente de catalisador de metaloceno de háfnio.
