ABSTRACT:
The present invention relates to a method for the prepolymerization of α-olefin in the presence of a catalyst system which comprises (a) a magnesium supported solid complex titanium catalyst and (b) an organometallic compound of metal of Group I or III of the Periodic Table, characterized in that an inert solvent having high viscosity with molecular weight of 300 g/mole or more is used as a reaction medium.
