Abstract

1. A process for the preparation of homopolymers and copolymers of C2 -C6 -alpha-monoolefins at from 20 to 160 degrees C, and under a pressure of from 1 to 100 bar, by means of a Ziegler-Natta catalyst system comprising (1) a titanium-III component which is obtained by reacting (1.1) 1 mole, calculated as titanium-III chloride, of a titanium-III chloride conventionally used for Ziegler-Natta catalyst systems, which has been modified with a compound possessing an aluminium chloride group and may or may not have been modified with an organic complexing agent, with (1.2) from 0.05 to 5 moles of an ether of the formula R**1-O-R**2 where R**1 and R**2 are identical or different and each is alkyl of 2 to 15 carbon atoms, phenyl or alkylphenyl, where alkyl is of 1 to 8 carbon atoms, the ether being in the form of an 0.1 - 10 molar solution in an inert hydrocarbon, at from 0 to 120 degrees C for a period of from 10 to 120 minutes, and with (1.3) from 0.1 to 20 moles of titanium tetrachloride, in the form of an 0.1 - 4 molar solution in an inert hydrocarbon, at from 0 to 120 degrees C for a period of from 10 to 220 minutes, and isolating the reaction product, and (2) an aluminium-alkyl component of the formula see diagramm : EP0036549,P8,F1 where R**3 and R**4 are identical or different and each is alkyl of 1 to 8 carbon atoms, with the proviso that the atomic ratio of titanium from the titanium-III component (1) to aluminium from the aluminium-alkyl component (2) is from 1:1 to 1:20, in which process the catalyst system employed contains, as a further component, (3) a phenolic compound of the formula see diagramm : EP0036549,P8,F2 where R**5 is C1 -C6 -alkyl, R**6 is hydrogen or C1 -C6 -alkyl, R**7 is hydrogen or a saturated hydrocarbon radical of not more than 30 carbon atoms, which may or may not contain up to a total of 6 ether groups and/or ester groups, R**8 is C2 -C24 -alkyl, and o is an integer from 1 to 6, with the proviso that the molar ratio of aluminium-alkyl component (2) to phenolic compound (3) is from 1:1 to 40:1.
