| titleOfInvention | A kind of preparation method of olefin polymerization catalysis, its preparation method and polyethylene |
| abstract | The present invention provides a kind of olefin polymerization catalysis, including carrier and load ziegler natta catalyst on the carrier；The carrier is porous polymer microsphere, and the aperture of the porous polymer microsphere is 10~25nm.The olefin polymerization catalysis that the present invention is provided using aperture be 10~25nm porous polymer microsphere as catalyst carrier, load metallocene (Ziegler Natta) catalyst, obtain olefin polymerization catalysis.The olefin polymerization catalysis that the present invention is provided to ethene during catalytic polymerization is carried out, the specific aperture of the porous polymer microsphere as carrier causes PE strands mutually to be tangled in generation, and this entanglement for being difficult to open hinders the motion of strand, cause fusing point to raise, 143 DEG C can be reached.Present invention also offers a kind of preparation method of olefin polymerization catalysis and a kind of preparation method of polyethylene. |
