| titleOfInvention | Method for polymerizing ethylene and polyethylene |
| abstract | The invention relates to the field of ethylene polymerization, in particular to an ethylene polymerization method and polyethylene prepared by the method. The invention discloses a method for polymerizing ethylene, which comprises the following steps: the method comprises the following steps of carrying out polymerization reaction on ethylene in the presence of a catalyst under polymerization reaction conditions, wherein the catalyst comprises a spherical composite material and a magnesium salt and/or a titanium salt loaded on the spherical composite material, and the spherical composite material comprises a mesoporous molecular sieve material with a hollow spherical structure and silica gel. The invention also discloses polyethylene prepared by the method. The supported polyethylene catalyst provided by the invention has high catalytic activity when used for ethylene polymerization reaction, and can obtain a polyethylene product with excellent performance. |
