Abstract
The emulsion copolymerization of butadiene with styrene is an example of a commercial process whose selectivity and specificity may be highly improved by technological means feasible now through modelling and simulation, although the basic chemical reactions are neither selective nor specific. To obtain optimum properties of the final rubber, optimum chemical composition is necessary; but since the composition changes during the copolymerization with the conversion of monomers, the resulting copolymer has a heterogeneous chemical composition. This is one of the obstacles to effecting the high-conversion copolymerization. Simulation of the copolymerization under dosing of the more reactive monomer, i. e., butadiene has shown that an improvement in the chemical homogeneity of the copolymer by 17 times at the conversion of 98% is feasible. A mathematical model accounting for all important effects in the emulsion copolymerization was developed; the most plausible parameters of the model were evaluated by starting from published data; and the simulation was performed by means of programs developed in Fortran for the ICL 2903 computer.
