Abstract
A stabilizer composition, suitable for use in polyvinyl chloride compositions, can be formed by reacting a mixture of monoalkyltin trichloride, such as butyltin trichloride, and dialkyltin dichloride, such as dibutyltin dichloride, with at least one carboxylic acid, such as 2-ethylhexanoic acid, and 2-mercaptoethanol, in the presence of base, followed by reaction of the resulting product with a sulfide reagent, such as sodium sulfide. The final composition comprises a complex mixture of alkyl tin carboxylates and/or mercaptides, and of monoalkyltin sulfides and dialkyltin sulfides.
