A polymer composition comprising, based on the total weight of A), B), C) and D),A) from about 10 to 89.99 percent of a substantially random interpolymer comprising in polymerized form i) from about 35 to about 89.5 mole percent of one or more alpha-olefin monomers and ii) from about 65 to about 10.5 mole percent of one or more vinyl or vinylidene aromatic monomers and/or one or more sterically hindered aliphatic or cycloaliphatic vinyl or vinylidene monomers, and optionally iii) other polymerizable ethylenically unsaturated monomer(s);B) from about 10 to about 75 percent of one or more polyolefins selected from the group consisting of I) propylene polymers and II) high density polyethylenes; andC) from 0.01 to about 10 percent of a non-ionic lubricant; andD) from 0 to about 60 percent of a substantially random interpolymer comprising in polymerized form i) from about 50 to about 99.5 mole percent of one or more alpha-olefin monomers and ii) from about 50 to about 0.5 mole percent of one or more vinyl or vinylidene aromatic monomers and/or one or more sterically hindered aliphatic or cycloaliphatic vinyl or vinylidene monomers, and optionally iii) other polymerizable ethylenically unsaturated monomer(s) with the proviso that the molar percentage of the one or more alpha-olefin monomers in the substantially random interpolymer D) is at least about 10 mole percent higher than the molar percentage of the one or more alpha-olefin monomers in the substantially random interpolymer A).
