Experiments were performed to investigate the effect of the viscosity of the continuous phase on the stability of droplets in suspension polymerization of styrene.
An empirical equation was obtained to represent the dependence of the rate of coalescence and breakup of droplets on the viscosity of the continuous phase.
It was found that the rate of coalescence is lowered and a narrower particle size distribution is obtained by increasing the viscosity of the continuous phase.
Furthermore, it was presumed that a coalescence rate larger than 1.5×105 number/hr leads to agglomeration. With the usual stirring equipment of beaker scale the phase ratio can be raised to 0.67 by increasing the viscosity of the continuous phase.
