ANIONIC COPOLYMERIZATION OF CONJUGATED DIENES AND VINYLARENES IN PRESENCE OF TETRAHYDROPIRANYL-METHANOL ALQUILETHERS.

摘要

A process for the preparation of a polymer for the polymerization of: (A) of 50 to 100 percent by weight of at least a diene monomer; (B) 50 to 100 percent by weight of at least one ethylenically unsaturated monomer; the previous polymerization is carried out in an inert solvent in presence of a catalytic system which comprises; (a) at least an anionic initiator essentially consisting of a Litio derivative, (b) at least a modifier pertaining to the group of the tetrahydropiranylethers.
