Polyolefin/polyisoprene alloy material and preparation method thereof

The invention discloses a polyolefin alloy material and a preparation method thereof, belongs to the field of polyolefin materials and particularly relates to a polyolefin/polyisoprene alloy material as well as a preparation method and application thereof. In a polyolefin/polyisoprene alloy, the mass content of polyolefin is 5 to 99.4 percent, and the isotacticity is greater than 85 weight percent; the mass content of polyisoprene is 0.5 to 85 percent; the mole content of a trans-1,4 structure is greater than 85 percent, and the mass content of a block copolymer is 0.1 to 10 percent. The polyolefin/polyisoprene alloy material synthesized by adopting supported titanium and/or a vanadium catalyst through a two-segment polymerization method, disclosed by the invention, is a granular product with a core-shell structure, has the characteristics of high strength and high toughness, and is a novel polyolefin material.
