Abstract

tin salts formed by the reaction of di lower alkyl or aryl tin oxides and dimercapto ethyl formal and similar dimercapto compounds of the general formula ##STR1## wherein R is --(CH2)m (OCH2)s --O--(CH2)m --(OCH2)p --O--n (CH2)m -- wherein p is 0 or 1, m is 2 to about 6 and n is 0 to about 6 and R' is lower alkyl of up to about 10 carbon atoms, or carbocyclic aryl containing one or two aromatic rings when combined with conventional tin based stabilizers show a synergistic light and heat stabilizing effect in poly(vinyl chloride) polymers.
