Studies of Rigid Poly(Vinyl Chloride) (PVC) Compounds .3. Correlation of Compounding Energy with Fusion Level
The major contributors to the compounding energy of a poly(vinyl chloride) (PVC) sample in the Haake torque rheometer are starting temperature, rotor speed, and totalized torque. In this study, the compounding energy was calculated by using an energy balance in the internal mixer reported by Pedersen. The fusion levels of the PVC samples, which were prepared in the Haake torque rheometer at various blending conditions (starting temperature = variable, rotor speed = 60 rpm, and totalized torque = 10 kg-m-min), were determined by DSC and a capillary rheometer. The compounding energy was then correlated with the fusion level. The simple total energy balance can be applied to correlate the compounding energy with the fusion level of the PVC compound prepared in the Haake torque rheometer.
