Catalyst for producing an ultra high molecular weight polyethylene and method for producing an ultra high molecular weight polyethylene using the same |
| abstract |
The present invention provides a method for producing a catalyst for the production of an ultra high molecular weight polyethylene and also a method for preparation of an ultra high molecular weight polyethylene with the use of said catalyst. The catalyst of the present invention is prepared by a process comprising: (i) producing a magnesium compound solution by contact-reacting a magnesium compound and an aluminum or boron compound with alcohol; (ii) contact-reacting the said solution with an ester compound containing at least one hydroxy group and a silicon compound containing an alkoxy group; and (iii) producing a solid titanium catalyst by adding a mixture of a titanium compound and a silicon compound thereto. The catalyst prepared by the present invention has excellent catalytic activity, and it helps to produce an ultra-high molecular weight polyethylene with large bulk density and narrow particle distribution without too large and minute particles. |
