Abstract
The present invention relates to a composition comprising 1) from 1 to 98 weight % of a first propylene polymer having a melting point of 100° C. or more, 2) from 5 to 98 weight % of a second propylene polymer having a heat of fusion of 70 J/g or less and a tacticity index of 75% or more, 3) from 0.5 to 75 weight % of a non-functionalized plasticizer (“NFP”) having a viscosity index of 120 or more, based upon the weight of the first polymer, second polymer, and the NFP, and articles therefrom.
