There are many ways to express the average molecular weight of PVC, but most of them are established based on the determination of the viscosity of PVC dilute melt. The usual expression method is absolute viscosity (n), which is the viscosity value measured at 20 ℃ in a dichloroethane solution with a concentration of 1% PVC resin; Viscosity number - is the viscosity value measured at 25 ℃ of PVC cyclohexanone solution with a concentration of 0.005g/mL
