ABSTRACT:
A method for coupling a living cationic polymer is disclosed, said method comprising reacting the living cationic polymer with an organic compound having at least 2 furan rings in its molecule, said reaction taking place in the presence of a Lewis acid. Preferably, the living cationic polymer is first prepared by polymerizing at least one monomer selected from isobutylene, isoprene or a styrenic monomer using a specific initiator, this reaction also being carried out in the presence of a Lewis acid.
