Abstract

"PROCESSO PARA PRODUçãO DE POLìMEROS DE OLEFINA". Um processo para produzir pelo menos dois graus de polímero de propileno diferentes, em cujo processo o isostaticidade do polímero é alterada, enquanto mantendo a taxa de fluxo de fusão do polímero em um nível predeterminado durante uma transição de produção de um primeiro grau de polímero para um segundo. O processo é realizado em uma disposição de polimerização compreendendo pelo menos um reator de polimerização, onde o propileno é polimerizado, opcionalmente com co-monómeros, sob condições de polimerização na presença de hidrogênio como um agente de controle de peso molecular e um sistema catalisador Ziegler-Natta. O sistema catalisador compreende um componente catalisado e um doador externo. Durante uma transição de produção do primeiro grau de polímero para o segundo, o doador externo é alterado, porém o alimento de hidrogênio é mantido em um nível predeterminado.
