ABSTRACT:
Hetero phase polymer compositions are described. The compositions may have polypropylene component, a modifier component and a compatibilizer component. The modifier component may in some embodiments be an ethylene α-olefin copolymer with a density ≧0.905 g/cm3. In other embodiments the modifier component may be a blend of a copolymer with a density of ≧0.905 g/cm3, and an ethylene α-olefin copolymer of lower, more traditional density.
