The Trend of Additives for Poly(vinyl chloride) as Photostabilizers: Article Review

Abstract

Conservation of poly(vinyl chloride) from the ultraviolet light that causes degradation, have very attention in recent decades. PVC formularizations have a large number of additives playing fundamental functions during their conversion and adjusting the behavior properties of final products. In this review, various types of additives are briefly discussed to show their important properties and reasons for addition to their essential mechanisms that cause retardation of photodegradation. The additives including organotin(IV), UV screeners, organic UV absorber and freeradical scavengers.

Synthesis and Applications of Organotin(IV) Compounds: Mini Review

“…Ph3SnL complex was the most efficient photostabilizer possibly because of its high aromatic content as shown previously in Fig. 3 [50]. For instance, photolysis of TBT may be hindered leading to the accumulation and preservation in sediment.…”
