“…and smoke suppressants. 364 Metal chelates decrease degradation temperature of PVC. 374 The most popular are antimony oxide, aluminum trihydrate, magnesium hydroxide, phosphate plasticizers, zinc borate, 357 copper compounds (char formers), and molybdenum-based smoke suppressants.…”

“…9 These stabilizers were efficient at the beginning of PVC thermal treatment, but once completely consumed a rapid increase in HCl release was noted with a coloration of the polymer. 33 This was probably due to the catalytic effect of CdCl 2 or ZnCl 2 on the thermal degradation of PVC. 12…”

The aim of this work was to prepare metal soaps of epoxidized sunflower oil (ESO) and use them as thermal stabilizers for polyvinyl chloride (PVC). For that purpose, commercial sunflower oil was first epoxidized and then used to prepare (Ba, Zn, Pb, and Cd) metal soap derivatives, which were characterized by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The prepared metal soaps derivatives of ESO were used as thermal stabilizers for plasticized PVC. Discoloration, residual thermal stability at 200°C , and rheological properties of PVC samples were tested. The structural modifications were investigated by UV-visible spectroscopy. The best thermal stabilization effects were observed in the presence of Pb soap of ESO. Furthermore, metal derivatives of ESO were classified according to their stabilizing effect as follows: Pb-ESO > Ba-ESO > Cd-ESO > ESO > Zn-ESO.

“…119 Therefore its reactivity with HCl alone is not sufficient to make it perform as a PVC thermal stabilizer. Calcium carboxylate alone has only limited relevance to PVC stabilization because its compositions darken well before HCl begins to be detected in the surrounding atmosphere.…”
