MULTIMODAL COPOLYMER OF ETHYLENE AND AT LEAST TWO ALPHA-OLEFIN COMONOMERS AND FINAL ARTICLES MADE THEREOF
摘要
The present invention is directed to a multimodal polyethylene copolymer comprising a first and a second copolymer of ethylene and at least two alpha-olefin comonomers. Such multimodal copolymers are highly suitable for conversion processes that require a high Draw Down Ratio, like the production of thin films. Such multimodal polyethylene copolymers provide a good impact strength in the sense of a high Dart drop impact strength (DDI) and good isotropy of the films produces thereof. The invention further presents final articles such as films made therefrom.
