Ozone resistant compositions and articles

A composition comprising a propylene-based interpolymer and a saturated compound selected from the group consisting of aliphatic amides, hydrocarbon waxes, hydrocarbon oils, fluorinated hydrocarbons and siloxanes, and

• wherein the propylene-based interpolymer comprises (a) greater than 50 mole percent propylene, based on the total moles of polymerizable monomers, and (b) ethylene, or ethylene and one or more unsaturated comonomers, or one or more unsaturated comonomers, and
• wherein the propylene-based interpolymer has at least one of the following properties:
• (i) 13C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity, and
• (ii) a DSC curve with a Tme that remains essentially the same, and a Tmax that decreases as the amount of comonomer in the interpolymer is increased.

A pouch comprising a film layer formed from a composition comprising a propylene-based interpolymer, and

• wherein the propylene-based interpolymer comprises (a) greater than 50 mole percent propylene, based on the total moles of polymerizable monomers, and (b) ethylene, or ethylene and one or more unsaturated comonomers, or one or more unsaturated comonomers, and
• wherein the propylene-based interpolymer has at least one of the following properties:
• (i) 13C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity, and
• (ii) a DSC curve with a Tme that remains essentially the same, and a Tmax that decreases as the amount of comonomer in the interpolymer is increased.
