POLYMER COMPOSITIONS AND ARTICLES MADE THEREFROM

摘要

A polymer composition and articles made therefrom are provided. The composition comprises: (a) Component A having (i) at least 50 wt% ethylene moieties; and (ii) up to 50 wt% of a C3 to C20 comonomer moities, a density of about 0.860 to about 0.965 g/cm3, a melt index of about 0.1 to about 10.0 g/10min and a branching index of about 0.96 to about 1.0; and (b) Component B having: (i) at least 65 wt% ethylene moieties; and (ii) up to 35 wt% of a C3 to C20 comonomer moities, the wt%s based upon total the total weight of Component B, a density of about 0.905 to about 0.945 g/cm3, a melt index (MI) of about 0.1 to about 10.0 g/10 min, and a branching index (g') of about 0.7 to about 0.95. Films made using the polymer composition exhibit excellent toughness and processability.
