Dispersion Polymerization Zhang Kai, Zeng Min, Lei Yi, Jiang Luxia (Dep. of Polym. Mat. & Eng., Sichuan Univ., Chengdu 610065) Abstract Dispersion polymerization is a new polymerization method. This method involves monomer, stabilizer and initiator dissolved in the reaction media to polymerize with the formation of insoluble polymer dispersed in the reaction media by the stabilizer. Dispersion polymerization has been applied in many fields, such as coating, bioengineering, medicine, chemistry industry etc. In this paper, the two major problems of the polymerization process, including the stabilizing effec of the polymer dispersion and reaction mechanism are reviewed.
