摘　　要：Organotin mercaptide-based thermal stabilizer is recognized for its effectiveness in enhanc-ing thermal stability of polyvinyl chloride(PVC).In this study,we synthesized an organotin mercaptide-based thermal stabilizer from palm fatty acid distillate,which is a by-product of palm oil refining process,and then evaluated its thermal stabilizing effects on PVC and compared its efficacy and economics to those of mixed metal stearate.The synthesized thermal stabilizer mani-fests as methyltin mercaptoethyl carboxylate sulfides.Both dehydrochlorination and two-roll mill discoloration tests have demonstrated the high efficacy of the resulting thermal stabilizer in stabi-lizing PVC,surpassing the performance of mixed metal stearate,as evidenced by the lower dosage required.The synthesized PVC thermal stabilizer not only provides effective stabilization but also presents a competitive viable alternative.
