Abstract: PROBLEM TO BE SOLVED: To provide a process for homopolymerization or copolymerization of a 2-8C alk-1-ene which enables excellent mixing of a transition metal- containing solid catalyst. SOLUTION: A Ziegler-Natta or Metallocene solid catalyst system which contains a transition metal is supplied into a reaction vessel 1 together with at least a portion of a 2-8C alk-1-ene which is metered and supplied into the reaction vessel 1 via one or more pipes 4 and gas-phase polymerization is conducted inside an agitation bed 2 of finely divided polymer, wherein the pipes are protruding perpendicularly or substantially perpendicularly from above into the gaseous space and ending above the pulverulent agitation bed 2.

Abstract: Polymers of propylene are prepared by means of a Ziegler-Natta catalyst system comprising (1) a titanium component which contains titanium, magnesium, chlorine and a benzenecarboxylic acid derivative, (2) an aluminum component and (3) a silane component, wherein the (1) used is obtained by (1.1) first reacting with one another (1.1.1) in a liquid hydrocarbon, (1.1.2) a finely divided magnesium halide, (1.1.3) an alkanol, (1.1.4) a phthalic acid ester and (1.1.5) titanium tetrachloride under certain conditions, (1.2) then extracting the solid intermediate obtained from (1.1) with a liquid alkylbenzene until the remaining solid substance has become significantly richer in magnesium, and (1.3) finally washing the solid substance remaining in (1.2) with an alkane in a certain manner.
