    Abstract

    Ethene was copolymerized in liquid propene with a high activity heterogeneous MgCl2/TiCl4-triethylaluminium catalyst and with homogeneous VOCl3-diethylaluminiumchloride and Cp2ZrCl2-methylaluminoxane catalysts to study the effect of the catalyst system on the properties of the products. The titanium catalyst gave crystallizable ethene blockies at high ethene contents and the zirconium catalyst gave the most random distribution of the monomers. The differences in the properties of the polymers were not so great as expected.
