A one-step method to prepare monodisperse polymer particles in the micron size range

Micron-sized, monodisperse PMMA microspheres were produced in TEOS, under static condition by one step. The mechanism of this novel self-formation method was studied based on experiment results; it was found that the growth of PMMA microspheres was in two ways. The properties of the intermediate particles were studied by several methods. The size of finally obtained polymer particles could be controlled by adjusting the content of monomer in initial polymerization solution. The influence of the polymerization temperature on the preparation of polymer microspheres was also investigated.
