Abstract
The reaction of PVC with potassium allyl xanthate in DMF is discussed. Thermogravimetric analysis and differential scanning of calorimetry were used to evaluate the thermal stability. The allyl xanthate‐modified PVC (AX‐PVC) was shown to be significantly more thermally stable than the unmodified PVC homopolymer. The AX‐PVC is completely crosslinked at temperatures > 180°C. It was found that dibutyltin di‐2‐ethylhexanoate, a commercial PVC stabilizer, does not produce the same effect on the thermal stability of the AX‐PVC as it did on the unmodified PVC homopolymer.Keywords
