Process for the preparation of diene polymers of statistical vinylarene-diene copolymers |
| abstract |
A process for the preparation of diene polymers or vinylarene-diene statistical (random) copolymers which comprises the anionic (cp) polymerization, in hydrocarbon solvents, of at least one monomer of a conjugated diene, optionally in the presence of a vinyl aryl monomer, and using a compound belonging to the group of lithium alkyls as initiator, characterized in that the total lithium alkyl initiator is modified in situ by means of a reaction with a compound having general formula (I): R m —(X—H) n (I) wherein R is a C2-C20 (cyclo) alkyl or C6-C20 aromatic radical, X is a heteroatom belonging to group VA or group VIA of the periodic system, n is an integer higher than or equal to 1, m is an integer>1 which depends on the valence of the heteroatom X. |
