Differential Scanning Calorimetry (DSC) has been used to characterize various lubricant additives for PVC in order to determine effectiveness. Depending on the processing period, and therefore the temperature profile, each lubricant undergoes a change in the internal vs. external nature of its behavior. In the process described, monitoring of the glass‐transition temperature produces evidence for the effectiveness of additives as internal lubricants.
