摘要
The composite,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.
