| Resumen: | The document specifies a method for the determination of the thermal stability at elevated temperatures of compounds and products based on vinyl chloride homopolymers and copolymers which undergo dehydrochlorination (the evolution of hydrogen chloride). The method may be used as a quality-control test during manufacture and conversion of PVC compounds. It may be used also for the characterization of PVC compounds and products, especially with regard to the effectiveness of their heat-stabilizing systems. |
