Abstract

Thermooxidative degradation of poly(vinyl chloride) (PVC) was carried out in dioctylphthalate (DOP) in oxygen atmosphere at 200°C. It was found that extensive chain scission occurs during this process. In contrast, molecular weight distribution indicates that crosslinking is absent. Molecular weight decreases as a function of time, and chain scission takes place with a constant rate. At longer reaction times, relatively large fractions of oligomers can be obtained.
