Abstract:
A composition comprising: (i) at least one low molecular weight polyolefin; (ii) at least one block copolymer obtainable by selectively hydrogenating a block copolymer having terminal polymeric blocks of a vinyl aromatic monomer and a mid-block prepared originally with an olefin and subsequently hydrogenated; (iii) at least one polypropylene; and (iv) at least one plastomer, wherein the plastomer is an ethylene based polymer having a density of 0.86 g/cc to about 0.910 g/cc or a propylene based polymer having a heat of fusion (Hf) of 70 J/g or less.
