摘要

摘要以卡托普利(配体)等5种有机锡(IV)配合物作为聚氯乙烯(PVC)的光稳定剂。聚合物样品被浇铸成薄膜，以进行紫外线曝光冲击。研究了空白和有机锡(IV)配合物包埋PVC样品的光降解速率常数(kd)。填充样品的kd值低于空白样品，表明这些包埋膜具有较高的稳定性。其中，三苯基锡(IV)的稳定效果最好。关键词:PVC，有机锡(IV)配合物，光稳定性，光降解，紫外光化学。Soc。阿比西尼亚人。2023年,37 (3),771 - 777 . a DOI: https://dx.doi.org/10.4314/bcse.v37i3.18

Inorganic tin(IV) complexes as photo-stabilizer for PVC

ABSTRACT. Five organotin(IV) complexes including captopril (ligand) were employed in small amount as photostabilizers for poly(vinyl chloride) (PVC) when irradiated by UV light. Polymer’s samples were cast into films in order to conduct the UV exposure impact. The photodegradation rate constant (kd) of blank and organotin(IV) complexes embedded PVC specimens were investigated in this work. The kd values of filled samples were lower than the blank one, which indicates higher stability of these embedded films. Among these additives, triphenyltin(IV) showed the highest stability effect.
