Abstract

Patente de Invenção: <B>"POLìMEROS DE PROPILENO INCORPORANDO MACRÈMEROS DE POLIETILENO"<D>. é fornecido um produto de poliolefina o qual compreende um copolímero de olefina ramificado tendo uma estrutura principal de polipropileno isotático, ramificações de polietileno e, opcionalmente, um ou mais comonómeros. O teor de comonómero total do copolímero de olefina ramificado é de 0 a 20 moles por cento. Além disso, a razão da massa do polipropileno isotático para o polietileno varia de 99,9 : 0,1 a 50 : 50. Adicionalmente, é fornecido um processo para a preparação de copolímero de olefina ramificado o qual compreende: a) copolimerização do etileno, opcionalmente com um ou mais monómeros copolimerizáveis, em uma reação de polimerização sob condições suficientes para formar copolímero tendo mais de 40 % de insaturação de grupamento final da cadeia; b) copolimerização do produto de a) com propileno e, opcionalmente, um ou mais monómeros copolimerizáveis, em um reator de polimerização sob condições de polimerização de polipropileno adequadas usando um catalisador de metal de transição estereorrígido, quiral, capaz de produzir polipropileno isotático; e c) recuperação de um copolímero de olefina ramificado.
