Abstract A semi-continuous preparation system for polymer microspheres, which consists of a vibration emulsifier and five series reactors with vibration plates, was developed and was varified on continuous preparation of polystyrene-co-divinylbenzene microspheres by in situ polymerization. An O/W emulsion was prepared using the emulsifier and flowed gradually into the each reactor. The in situ polymerization was carried out in each reactor to form solid particles. The particles prepared in each reactor was taken out from the bottom of the reactor. The average diameter of the particles prepared decreased with increasing in the vibration frequencies of the emulsifier. The average diameter and the quantitiy of the particles were independent on the vibration frequencies of the vibration plates and on the number of the reactor. Continuous operation was successfully carried out and the sphere particles having uniform shape were continuously prepared for 10 cycles operation, which needed for 55 hr.
