Abstract: Six dialkyltin mercaptides have been prepared by reaction of bis(β-alkoxycarbonylethyl)tin dichlorides with i-octyl thioacetate, i-octyl thiopropionate and dodecanethiol. Their properties as heat stabilizer for polyvinyl chloride during processing have been investigated.

Key words: dialkyltin mercaptide, preparation, PVC heat stabilizer
