Description

I

The invention relates to the automation of production processes and can be used in the manufacture of synthetic rubber in accordance with polystyrene.

A known method for controlling P1 by the process of emulsion polymerization, which is realized in a battery of successively installed nvMejjHaflators, is connected with a change in the temperature of the reaction mixture and conversion of monomers depending on the average molecular weight of the polymer With the CSP method characterized by an increase in the accuracy of stabilization of polymer viscosity according to MyHVi due to the ambiguity of the dependence of viscosity uojuiwepa on A1uni on the average mole weight.

The chain of the invention is to improve the accuracy of stabilization of the viscosity of the polymer of Mooney.

Purpose Achieved by the fact that in the known method of controlling the process of emulsion polymerization carried out

in a battery of sequentially installed polymerizers, which consist in determining the temperature of the reaction mixture and the monomers' coversion, depending on the average molecular weight of the polymer, the increase in polymer Flour viscosity in one or more polymer mixers located along the reaction mixture is also determined. t, depending on the load on the polymer battery and the volume of the polymerizer, the time interval over which the specified increase in the Mooney viscosity of the polymer The rate of Mooney polymer viscosity increases according to battery polymerizers and, depending on the rate found, the monomer conversion at the output of the battery varies within technologically acceptable limits.

In this case, the value of the conversion of monomers at the outlet of the polymer battery can be stabilized by changing the 38
