Chlorinated polyvinyl chloride was synthesized via gas-solid phase method in a fluidized bed reactor by ultraviolet initiation. The kinetic behavior of polyvinyl chloride (PVC) chlorination was studied. The effects of reaction temperature, reaction time, concentration of chlorine and ultraviolet light intensity on chlorination of PVC were investigated. The kinetic model of chlorination of PVC was established according to radical reaction mechanism and the parameters were estimated. The results show that the kinetic equation model is well agreed with the reaction experimental data, and the activation energy is 82.6 kJ/mol, the pre-exponential factor is 9.97×1010 s-1.
