FABRICATED ARTICLES COMPRISING POLYOLEFINS

Fabricated articles are disclosed which comprise a polypropylene impact copolymer. The propylene impact copolymer composition comprises from 60 to 90 percent by weight of the impact copolymer composition of a matrix phase, which can be a homopolymer polypropylene or random polypropylene copolymer ha...

More Information
Summary:Fabricated articles are disclosed which comprise a polypropylene impact copolymer. The propylene impact copolymer composition comprises from 60 to 90 percent by weight of the impact copolymer composition of a matrix phase, which can be a homopolymer polypropylene or random polypropylene copolymer having from 0.1 to 7 mol percent of units derived from ethylene or C4-C10 alpha olefins. The propylene impact copolymer composition also comprises from 10 to 40 percent by weight of the impact copolymer composition of a dispersed phase, which comprises a propylene/alpha-olefin copolymer having from 6 to 40 mol percent of units derived from ethylene or C4-C10 alpha olefins, wherein the dispersed phase has a comonomer content which is greater than the comonomer content in the matrix phase. The propylene impact copolymer composition is further characterized by having the ratio of the matrix MFR to the dispersed phase MFR being 1.2 or less. The fabricated articles of the present invention cane be made at high speeds and are characterized by their soft feel, as compared to fabricated articles made from other propylene impact copolymers.
