Morphological characteristics of poly(styrene-co-divinylbenzene) microparticles synthesized by suspension polymerization

In the synthesis of poly(styrene-co-divinylbenzene) microparticles by the suspension polymerization technique, the models obtained indicate that the absence of NH4OH in the polymerization mixture leads to agglomeration of the microparticles. Besides, a low value of the impeller off-bottom clearance factor and a high value of the sodium dodecyl sulfate (SDS) concentration favor a narrower particle size distribution.
