Abstract
A process for the polymerization of α-olefins of the general formula CH2 = CHR, where R stands for an aliphatic hydrocarbon chain with 1 to 8 carbon atoms, unsubstituted or substituted by alcohol or aryl radicals, or mixtures of such α-olefins with each other and/or with ethylene, the content of one of the α-olefins in the mixture rising to at least 95% by weight, as well as for the blocked polymerization of said α-olefins and/or with ethylene, in suspension or in the gas phase and using mixed catalysts consisting of an organic compound as a stereoregulator, in a perched metal compound of subgroups IV to VI of the Periodic System, which is present in a lower valence step than the highest, and in an organometallic compound of the metals of the main groups I to III of the Periodic System, at temperatures of 20-120ºC and pressures below 50 gauge atmospheres, eventually regulating the molecular weight by means of hydr oxygen, characterized in that the polymerization is carried out in the presence of a mixed catalyst consisting of a) cyclooctatetraen or cyclooctatriene- (1,3,5) or cyclooctatriano- (1,3,6), or their mixtures or their derivatives substituted one or more times by alcohol, aryl or alkoxy, containing the alcohol or alkoxy radical 1 to 4 carbon atoms, either in mixtures of the derivatives with each other or with the basic body (component A); b) a halogenated heavy metal compound from subgroups IV to VI of the Periodic System, present in a valence step lower than the highest (component B); c) and in a halogen-free organometallic compound, based on the metals of the main groups I to III of the Periodic System (component C).
