Abstract

A polymeric composition comprising: an olefin polymer; a hydrogenated block copolymer comprising at least two polymeric block containing predominantly monoalkenyl aromatic hydrocarbon monomer units and at least one block containing predominantly hydrogenated, conjugated diolefin monomeric monomer units; and an LLDPE. The weight ratio of block copolymer to LLDPE in the polymeric composition will be within the range from about 5:1 to about 1:3. Shaped structures prepared with the polymeric composition will generally exhibit good clarity and good impact strength.
