It is well known that PVC possesses a relatively low stability and undergoes degradation even at relatively low temperatures. Thus, stabilization of PVC is one of the most important problems for PVC processing and applications. However, even after a period of half a century PVC production and worldwide use, there are several open questions related to the mechanism of action of PVC stabilizers. The deterioration of the resin is primarily a result of the zip-elimination of HCl from the main chain leading to the formation of sequences of conjugated double bonds. This paper concerns mainly with the recent advances in the understanding of the action of metal soap type and tin stabilizers during degradation of PVC.
