ABSTRACT:
A process of polymerizing or copolymerizing a class of olefins is carried out in the presence of a catalyst, which catalyst comprises one of more solid compounds selected as a carrier from the group consisting of an oxide, a double oxide and a hydroxide of halogen-free magnesium and/or calcium. The carrier is treated by direct contact with gaseous sulfur dioxide (SO.sub.2) under a gaseous atmosphere. A titanium and/or vanadium compound, viz. Ziegler catalyst component, is deposited on the treated carrier and activated by an organometal compound.
