Process for the preparation of branched polydienes in the presence of catalysts based on rare-earth |
摘要 |
A process is described for the preparation of polydienes with a low vinyl content and having a branched structure effected by means of the polymerization of conjugated dienes in the presence of catalysts based on rare-earth compounds. The resulting polymers are characterized in that they have a cis content varying from 80 to 96% and prove to be branched with consequent low viscosity values in solution.
