POLY ETHYLENE EXTRUSION COMPOSITIONS HAVING HIGH DRAWDOWN AND SUBSTANTIALLY REDUCED NECK-IN CHARACTERISTICS

摘要

ABSTRACT An ethylene polymer extrusion composition having high draw down and substantially reduced neck-in, a process for making such a connposition and a process of using such a composition to prepare extrusion coatings, extrusion profiles and extrusion cast films are disclosed. The ethylene polymer extrusion composition is made of 75-95 weight percent of at least one ethylene a-olefin interpolymer and 5-25 weight percent of at least one high pressure ethylene polymer characterized as having high melt strength and a broad, bimodal molecular weight distribution. In profiles, coatings or films, the composition can be used as sealant, adhesive or abuse resistance layers.
