Abstract:
A method for preparing a catalytic composition for the olefin polymerization in the form of a dispersion of catalyst particles in a semi-fluid matrix, characterized in that it comprises the steps of: a) forming a suspension of catalyst particles in oil by loading under a continuous stirring dry catalyst powder into a tank containing said oil, the load velocity of the catalyst powder per m 2 of oil interface being less of 800 kg/h*m 2 ; b) adding under stirring a molten thickening agent having a melting point in a range from 30 to 70°C, while maintaining the catalyst suspension in oil at a temperature such that said thickening agent solidifies on contact with said suspension.
