A mathematical model of polymerization of butadiene based 
on a cobaltous catalyst in a cascade of two continuous-operation reactors 
has been developed. The simultaneous processes of chemical transformations 
and heat exchange occurring in this case were described by a system 
of equations for heat balance and initial times of molecular-mass 
distribution in a steady-state regime. The model developed was used 
for investigating the dependence of the molecular-mass characteristics 
of the polymerization process studied and the temperature in the cascade 
of reactors on the monomer and initiator concentrations as well as 
for determining the optimum regimes of the polymerization process.
