The validity of 2,3-dichloro-1,3-butadiene (DC) suspension polymerization as an alternative evaluation method to poly(vinyl chloride) (PVC) suspension polymerization was investigated. The correlation of experimental data between PVC suspension polymerization and DC suspension polymerization was examined using two types of suspending agents. It was found that the particle properties can be expressed with a power function of the power consumption per unit volume.
