Hetero phase polymer compositions

摘要

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 alpha-olefin copolymer with a density>=0.905 g/cm<3>. In other embodiments the modifier component may be a blend of a copolymer with a density of >=0.905 g/cm<3>, and an ethylene alpha-olefin copolymer of lower, more traditional density.
