The properties of three elastomeric stereoblock polypropylene (PP) samples made with unbridged 2-phenylindene zirconocene catalysts were investigated. One of the characteristics of these catalysts is the ability to control the structure and properties of the polypropylenes by manipulation of the reaction conditions. Samples PP1 and PP2 were prepared to have similar tacticities (as indicated by IR and NMR spectroscopy) yet different molecular weights. The molecular weight of PP2 is approximately… CONTINUE READING
