Abstract
Linear alpha-olefins from propene to 1-eicosene have been polymerized using a zirconocene catalyst and a hafnocene catalyst. The resulting i sotactic polymers were characterized by NMR, GPC and DSC analysis. Com pared to the zirconocene products the molecular weights of the poly-al pha-olefins made with the hafnocene catalyst were higher. The molecula r weight distribution was found to be narrow as expected for metalloce ne polymers. DSC measurements showed that side chain crystallization o ccurs for the polymers from poly-1-decene to poly-1-eicosene.
