ABSTRACT:
Compositions are provided having from 70 wt % to 95 wt % of a polymer selected from homopolymers and random copolymers of propylene and from 5 wt % to 30 wt % of a miscible hydrocarbon resin with a glass transition temperature greater than 20° C. The polymer has a heat of fusion of less than 50 J/g, a melt index (MI) of less than 20 dg/min, and contains stereoregular propylene crystallinity. Also provided are films containing such compositions, and articles, such as diapers or incontinence garments, including such films.
