PROCESS FOR THE MANUFACTURE OF LOW MOLECULAR, UNSATURATED HYDROCARBON POLYMERS HAVING AN INCREASED PROPORTION OF VINYL, OR SUBSTITUTED VINYL

摘要

A B S T R A C TProcess for the manufacture of low molecular, unsaturated hydro-carbon polymers having an increased proportion of vinyl, or substitutedvinyl, groups by polymerising conjugated dienes, optionally in the presenceof a solvent, with the aid of a catalyst system consisting of a) a cobaltcompound, b) a halogen-containing organo-aluminium compound and c) and organicphosphorus compound.Low molecular, unsaturated hydrocarbon polymers, particularly poly-butadienes, are valuable raw materials for the preparation of coating agentsand coatings.
