    Abstract - (Show below) - (Hide below)

    Establishes a method for determining thermal stability at raised temperature of compounds and products based on vinyl chloride homopolymers and copolymers which undergo dehydrochlorination. Intended as a simple and rapid quality-control test during the manufacture and conversion of PVC compounds. Suitable for coloured compounds and products where a discolouration test under the action of heat may be unsatisfactory. Not recommended for compounds in the form of dry blends.
