Iso‐thermalgravimetric analysis has been used by many authors in studying the degradation mechanism of PVC. For the PVC compounder though this same method provides a reliable means of determining the efficiency and cost effectiveness of commercial PVC stabilizers. Thermal stability of PVC resins stabilized with organotin, antimony, and ester stabilizers are presented and compared with data obtained by conventional Brabender Plasticorder and post extrusion oven aging tests. In addition a method is presented to establish the relative stability and cost effectiveness of a stabilizer at given concentrations currently familiar to the rigid PVC compounder.
