<p>The process is carried out in solution or in bulk in the presence of a catalyst, the catalyst being deactivated when the polymerisation is complete and the polymer subsequently being isolated in a known manner, characterised in that the polymerisation is carried out in the presence of a catalyst which contains a product of the reaction of a) an organoaluminium compound R2AlX, R3Al2X3 and/or R AlX2 where R is a saturated (cyclo)aliphatic hydrocarbon radical having 1 to 10 carbon atoms, and b) TiX4 where X is a halogen atom. i</p> |
