Abstract

PURPOSE: To obtain a spherical carrier for an olefin polymn. catalyst industrially and easily at low cost, which carrier excels in the resistance to degradation, by a method wherein a suspension contg. particles of magnesium halide-active hydrogen complex is quenched in an org. liquid medium contg. a siloxane.
CONSTITUTION: A suspension contg. particles of magnesium halide-active hydrogen cpd. complex in the molten state is quenched in an org. liquid medium (A) contg. 0.1W40wt% a siloxane to solidify the complex particles. A preferred quenching-solidifying technique is that the suspension is rapidly contacted with an org. liquid medium (B) which is cooled to a low temp. at which the suspended complex particles are solidified. Preferred active hydrogen cpd. are alcohols. Examples of the siloxane are dimethyl siloxane, methylphenylsiloxane, and oxyalkylene- modified siloxane.
