Abstract
PURPOSE:To carry out drying after contact with or dispersion in a liquid hydrocarbon containing a specific silicon compound of a catalytic component containing Ti, Mg and halogen to prevent coarse particle formation due to the flocculation of said catalytic component. CONSTITUTION:(A) A catalytic component for olefin polymerization, containing, as the essential components, Ti, Mg and halogen (e.g., containing TiCl4, magnesium hydroxide and aluminum halide) is brought into contact with or dispersed in (B) a liquid hydrocarbon (e.g., n-pentane, benzene) containing a silicon compound of formula (R<1>-R<6> are each H or hydrocarbon residue; n is such a number that the viscosity of the silicon compound of the above formula falls between 1 and 1,000cst) (e.g., octamethyltrisiloxane) followed by drying, in general, under a pressure of 10-200mmHg at 10-80 deg.C.
