Abstract

Improvements introduced in the object of main patent no. 370,309, requested on 7.8.1969 for: "A process for the preparation of a conjugated diene polymer, which comprises polymerizing said conjugator" characterized in that the polymerization is carried out in the presence of a lithium-based initiator, to form a polymer that supports a lithium ion, and then contact the polymer that supports the lithium ion, with an amount between 0.25 and 10 moles, per mole of lithium ion, of a monoester derived from an aromatic monovalent alcohol and an aromatic monocarboxylic acid.
