Synthesis of Stereoblock Elastomeric Polypropylenes using (2-PhInd)2ZrCl2 Metallocene Catalyst in the Presence of Co-catalyst Mixtures: Part II. Microstructural Study

One of the main issues in the polymerization of alpha-olefins using multi-catalyst systems is the effect of different co-catalysts on the microstructure of producing polymers [1].In the present work the effect of different co-catalyst mixtures including methylaluminoxane (MAO), Tri-isobutylaluminum(TIBA) and Triethylaluminum (TEA) is investigated on propylene polymerization behavior of (2-PhInd)2ZrCl2 metallocene catalyst regarding the microstructure and thermal properties of polymers
