Abstract

TALHAMENTO ("TAILORING") COM OXIGêNIO DE RESINAS DE POLIETILENO. A presente invenção refere-se a métodos de talhamento de polietilenos utilizando de 0,5 a 70 por cento de volume de gases contendo oxigênio. O talhamento ocorre em uma zona de transporte de massa fundida de um misturador/extrusora, e não nas zonas de alimentação ou de massa fundida de um a misturador/extrusora. O efeito de talhamento é para diminuir a urvação e/ou aumentar o brilho de películas sopradas produzidas a partir dos polietilenos talhados em comparação com polietilenos similares que são extrudados/misturados na ausência substancial de oxigênio ou gases contendo oxigênio.
