Abstract

Procedure for the mass catalytic polymerization of a liquid conjugated diene monomer, in a reactor while regulating the polymerization temperature by controlled evaporation and condensation of a portion of said liquid monomer, characterized in that it comprises submitting a solution of a polymer of said monomer in the latter, such that the concentration of said polymer exceeds the critical concentration of the latter, as previously defined, at a temperature higher than the minimum foaming critical, as defined, but lower than that at which produces excessive foaming, thus polymerizing the monomer of said solution.
