Synthesis of Dibutyl tin (IV) Dilurate and its Application as a Safe Thermal Stabilizer in Polyvinyl Chloride

In this work a modified procedure was done to prepare dibutyl tin (IV) dilurate without impurity of substituated tributyl tin which has health effect. Purity of the final product was tested by using chromatography techniques. The product was used as a thermal stabilizer in soft PVC. Properties of the stabilized and unstabilized PVC films were investigated with different techniques such as IR spectroscopy, thermal gravimetric analysis and mechanical tests. The results show that dibutyl tin dilurate can be used as a thermal stabilizer for PVC with high efficiency.
