摘　　要：Five amido thiol tin compounds, bis N,N dialkylaminocarbonylethyl tin bis iso octyl sufenylacetates, were prepared by reacting esters thiol tin or ester tin dichloride with secondary amines. The structures of the compounds were determined by IR, 1H NMR , 119 Sn NMR and elemental analysis. The new compounds have a good heat stability for PVC resin, among them bis N,N dihydroxyethylaminocarbonylethyl tin bis iso octyl sufenylacetate is the best one.Five amido thiol tin compounds, bis N,N dialkylaminocarbonylethyl tin bis iso octyl sufenylacetates, were prepared by reacting esters thiol tin or ester tin dichloride with secondary amines.
