Abstract

Предлагается композиция этиленового полимера, обладающая плотностью от 935 до 950 кг/м, динамической вязкостью η, измеренной при частоте 0,05 рад/с, от 2000 до 7000 Па∙с и показателем снижения вязкости под действием сдвига SHIот 4 до 15. Благодаря комбинации вышеупомянутых свойств композицию по изобретению можно перерабатывать с высокой производительностью в конечные изделия с хорошими свойствами, например, с точки зрения внешнего вида и прозрачности, которые являются весьма желательными во многих областях применений, таких как формование, включая применения в виде пленок.
