Abstract

Patente de Invenção: <B>"MISTURAS DE LLDPE COM UM COPOLìMERO DE ETILENO-NORBORNENO PARA RESINAS DE MELHORES RIGIDEZ E PROCESSABILIDADE PARA A PRODUçãO DE PELìCULAS"<D>. Esta invenção é para misturas de LLDPE com um copolímero de etileno-norboneno para resinas de rigidez e processabilidade melhoradas para a produção de películas. Esta invenção provê resinas baseadas em LLDPE que são significativamente melhores com relação à sua capacidade de ser fabricada em camadas de películas, particularmente por uma técnica de extrusão de bolha soprada. Películas preparadas de resinas de LLDPE/E-NB misturadas em fusão desta invenção são significativamente melhores com relação à algumas propriedades da película, tais como resistência ao rasgamento, sem prejudicar as propriedades benéficas que um LLDPE de outra forma conferem a uma película.
