| titleOfInvention | The preparation method and its polymer of a kind of olefin polymer |
| abstract | The invention discloses a kind of preparation method of olefin polymer and its polymer.This method includes, in the presence of olefin polymerization catalysis, by formula CH 2 The alkene that=CHR is represented carries out polymerisation；The olefin polymerization catalysis contains catalyst solid constituent A, organo-aluminum compound B and organo-silicon compound C；The weight ratio that the catalyst solid constituent A contains magnesium, titanium, halogen, internal electron donor a and internal electron donor b, the internal electron donor a and the internal electron donor b is less than 1:1；Wherein, the internal electron donor a and internal electron donor b is met The temperature of the polymerisation is 85 130 DEG C.The olefin polymerization catalysis of the present invention can be prepared while having the olefin polymer of high melt flow rate (MFR) and wide molecular weight distribution. |
