Abstract

Patente de Invenção: <B>"COMPOSIçõES DE POLìMERO DE ETILENO COM COMONÈMERO NORBORNENO"<D>. Trata a invenção de um polímero de olefina cíclico de etileno, particularmente um copolímero de etileno/norborneno e uma resina de terpolímero de etileno/norborneno/alfaolefina, de rigidez melhorada e capacidade de processamento para produção em películas. Esta invenção propicia resinas à base de etileno que são processáveis como um LLDPE, mas que são significantemente aperfeiçoadas, com relação à sua capacidade de serem fabricadas em uma camada de película, particularmente por uma técnica de extrusão a bolha soprada. Películas preparadas de resinas desta invenção são significativamente melhoradas com relação a algumas de suas propriedades de película, tais como resistência ao dilaceramento, sem diminuição das propriedades benéficas que uma resina similar a LLDPE propicia, de um modo diferente, para uma película. Também se apresenta a aplicação de moldagem dos copolímeros E/NB e terpolímeros E/NB/O acima.
