| titleOfInvention | Non-metallocene bimetal catalysis system for synthesizing branched polyethylene and application thereof |
| abstract | The invention relates to a non-metallocene bimetal catalyst system for synthesizing branched polyethylene, which is a catalyst system composed of a main catalyst and a cocatalyst, wherein the mol ratio of the cocatalyst to the main catalyst is (200-8000):1; the main catalyst is a non-metallocene bimetal catalyst of which the structural formula is shown in the specification; and the cocatalyst is alkyl aluminoxane or alkyl aluminum. According to the invention, the catalytic activity of the non-metallocene bimetal catalyst system is 1*10<4>-1*10<7> g PE(polyethylene)/mol.h, the polyethylene obtained through catalytic ethylene polymerization is branched polyethylene, and the melting point is below 125 DEG C. The non-metallocene bimetal catalyst has good heat stability, and the structure of the polymer can be regulated and controlled by changing the structure of the main catalyst and controlling the reaction conditions, so that polymer products with different performance indices can be produced. The polymerization process is simple and easy to control. |
