| Abstract
| - A metallocene/MAO-based solid olefin polymerization catalyst has been developed usingchemically functionalized nanoparticles (carboxylate−alumoxanes) as a well-defined substrate. Reactionof p-hydroxybenzoate−alumoxane (p-HB-A) nanoparticles, formed from the acid with boehmite, withmethylalumoxane (MAO) results in a solid nanoparticle-based MAO (n-MAO), which in combination withzirconocenes [including Cp2ZrCl2, Cp2ZrMe2, and (nBuCp)2ZrCl2] produces an active solid catalyst for olefinpolymerization. The catalytic activity of the n-MAO-based catalyst is comparable to the homogeneousanalogue and a traditional silica-supported catalyst under identical reaction conditions and with thesame Al(MAO):Zr ratio. The n-MAO approach offers the potential of the MAO being easily chemicallymodified.
