Abstract:
A cold-drawn film comprising a blend ofa) a semi-crystalline copolymer component of a major olefinic monomer and a minor olefinic monomer having a melting point greater than 25Â° C. and a flexural modulus less than 100 MPa, wherein said major olefinic monomer is ethylene or propylene and said minor olefinic monomer is different from said major olefinic monomer and is selected from the group consisting of linear, branched, or ring-containing C2 to C30 olefins, capable of insertion polymerization, and combinations thereof, and b) a polystyrene component having a flexural modulus greater than 200 MPa, wherein said copolymer is present in said film as a continuous phase and said film has a tensile modulus of less than 160 MPa.
