The seeded emulsion polymerization plays an important role in particle design and functional latex preparation because of the stability of latex

narrow distribution of latex particle size

easy to control and so on. It is the most simple and convenient method of preparing high solid content and core shell structure latex. The research progress in its techniques

mechanism such as grafting mechanism

interpenetrating polymer network mechanism

polymer deposition mechanism

seed surface polymerization mechanism and electrovalent bond mechanism etc.

and the applications in particle design of seeded emulsion polymerization are reviewed. The effects of various factors on seeded emulsion polymerization are discussed especially.
