Polystyrene microparticles are negatively charge-stabilized colloidal particles. These microparticles are produced by polymerization of styrene under conditions that induce spontaneous coalescent bead formation. Polymerization is terminated when two chains react to form a sulfate-terminated polymer chain. Amine-modified beads will have a positive charge under slightly acidic conditions.

Hi, are these particles positively or negatively charged and with which functional group? Preferably, I would also like to know with which functional group they are charged/stabilized. I am looking for positive particles!
