Abstract: The catalyst system contains (a) a complex cpd. obtd. by grinding 100 mol. pts. of a substance of formula TiCl3.0.33AlCl3 (I) with 5-50 mol. pts. of a cpd. of formula (R )3POn (II) (b) an Al cpd. of formula (R )3Al (III) and (c) an organo-Si cpd. of formula (R )mSi(OR )4-m (IV); R = 1-8C alkyl or 6-10C aryl; n = 0 or 1; R = 1-8C alkyl; R = 1-10C alkyl or 4-8C cycloalkyl; R = 1-8C alkyl; m = 1, 2 or 3. Also claimed is the prodn. of polymers of 2-8C alk-l-enes by polymerisation of the alkenes in the gas phase at 40-150 deg C and 10-100 bar in the presence of the above Ziegler-Natta catalyst system. Also claimed are polymers obtd. by this process.
