CATALYST FOR PREPARATION OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE AND PREPARATION METHOD OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE USING THE SAME

摘要

The invention relates to ultra-high molecular weight polyethylene manufacturing method using an ultra-high molecular weight polyethylene for making the catalyst, and this, and more particularly, to prepare a magnesium compound solution by reacting contacting a mixture of a magnesium compound and an aluminum or boron (boron) compound (ⅰ) and the alcohol and, (ⅱ) reacting the excitation silicon compound having an ester compound and alkoxy including at least one of the hydroxy groups in the following, (ⅲ) produced by the process for preparing a solid titanium catalyst by adding a mixture of a titanium compound and a silicon compound ultra high molecular weight polyethylene and to a catalyst for that ultra high molecular weight polyethylene using a method for producing the catalyst.; The catalyst of the present invention is excellent in catalytic activity, using the catalyst is the apparent density and specific viscosity larger, the particle size distribution of the polymer can be obtained narrow large particles or fine particles of ultra high molecular weight polyethylene is less.
