prepared with polypropylene grafting maleic anhydride and silica crosslinked by 3-aminopropytriethyoxysilane
was used as the carrier to support titanium chloride for forming polymerization catalyst.Scanning electron microscope investigated the morphology of support
supported-catalysts and polyethylene particles.The results indicated:silica and polymers have been combined closely
a little silica outside of the polymer net
however;under the proper conditions
the particles of polyethylene had a good replicability for catalysts morphology.
