ABSTRACT:
Organo-tin mercaptides containing polysulphanediyl groups are produced from a mercaptocarboxylic acid, a diorgano-tin derivative and a diol with a polysulphanediyl and, optionally, monoalcohols and mono-organo-tin derivative. Such mercaptides give vinyl chloride polymers improved resistance to yellowing.
