- 19 - O.Z. 0050/39143 Abstract of the Disclosure: Polymers of propene are prepared using a Ziegler-Natta catalyst system consist- ing of (1) a titanium component which is based on a finely divided, shape-imparting silica gel and, in ad- dition to titanium, contains magnesium, chlorine and a benzenecarboxylic acid derivative, (2) an alumino com- ponent and (3) a silane component. The process employs a titanium component (1) which is obtained by a method in which (1.1) first (I) a carrier is prepared from (Ia) a silica gel, (Ib) an organomagnesium compound and (Ic) a gaseous chlorinating agent by a procedure in which (1.1.1) first (Ia) is reacted with (Ib), (1.1.2) then (Ic) is passed into the product obtained from (1.1.1) and (I) is isolated, (1.2) thereafter, a solid-phase interme- diate is prepared from (I), (II) an alkanol, (III) tita- nium tetrachloride and (IV) a phthalic acid derivative by a procedure in which (1.2.1) first (I) is reacted with (II), (1.2.2) then (III) is introduced into the product resulting from (1.2.1), with the proviso that (IV) is also introduced in (1.2.1) or (1.2.2), (1.3) then the solid-phase product resulting from (1.2) is extracted with titanium tetrachloride, and (1.4) finally, the solid-phase product resulting from (1.3) is washed with a liquid hydrocarbon.
