Process for the preparation of branched polybutadiene with a high content of 1,4-cis units |
| abstract |
Process for the preparation of polybutadiene effected by the polymerization of butadiene in an aliphatic and/or cy-clo-aliphatic solvent in the presence of a catalytic system prepared in situ which comprises: (i) a carboxylate of neodymium solu-ble in the process solvent containing a variable quantity of water, the H2O/Nd molar ratio ranging from 0.001/1 to 0.50/1; (ii) an alkyl compound of aluminum; (iii) an alkyl compound of aluminum in which at least one bond of Al consists of an Al-Cl bond; The total Al/Nd molar ratio ranging from 4/1 to 12/1, and the Cl/Nd molar ratio ranging from 2/1 to 6/1. |
