Beschreibung
Zusammenfassung:	The invention relates to a method of preparing a solid polyolefin catalyst support, comprising:forming a suspension of nanoparticles in a solvent;adding an organic silica precursor to the suspension;adding water to the suspension;adding a sol-gel reaction catalyst to the suspension;mixing the suspension at a shear stress of between about 100 kPa and about 5000 kPa;adding a catalyst support to the suspension;continuing the shear stress on the suspension for about 5 minutes to about 720 minutes;separating a solid from the suspension; anddrying the solid.
