The preparation method of catalyst for ethylene polymerization |
| abstract |
The present invention relates to a method for producing a titanium solid catalyst supported on magnesium dichloride that can be used to produce ultra-high molecular weight polyethylene having a high apparent density. By carrying out a polymerization reaction using a solid catalyst containing titanium tetrachloride and a phthalate compound, ultra-high molecular weight polyethylene having a uniform particle size and high apparent density can be produced. |
