The present invention intends to provide a process for preparation of a solid titanium catalyst component for an olefin polymerization excellent in polymerization activity per unit catalyst, and a process for preparation of a polyolefin using a catalyst containing the catalyst component. The process according to the present invention is characterized by comprising the steps of contacting (A) a magnesium compound with (B) a solution titanium compound to obtain a solid titanium catalyst component composed of titanium, magnesium and a halogen as the essential components, wherein a titanium compound mixture liquid composed of 88 to 99 % by weight of a titanium compound and 1 to 12 % by weight of hydrocarbon containing halogen- containing hydrocarbon is used as (B) the solution titanium compound.

Procédé d'élaboration d'un composant catalyseur en titane à l'état solide pour la polymérisation des oléfines. Le procédé consiste à soumettre un composé de magnésium (A) au contact d'un composé de titane (B) en solution pour obtenir un composant catalyseur en titane à l'état solide renfermant du titane, du magnésium et un halogène comme composants essentiels, dans des conditions telles que le composé de titane en solution, constituant le composant (B), est un mélange liquide renfermant de 88 à 99 % en poids d'un composé de titane et de 1 à 12 % en poids d'un mélange d'hydrocarbures renfermant des hydrocarbures halogénés. Ce procédé permet d'obtenir un composant catalyseur en titane à l'état solide pour la polymérisation des oléfines, faisant preuve d'une activité élevée par quantité unitaire de catalyseur.
