Abstract: WHEREIN Z is silicon or tin; n is 0 to 3, and R'' is substantially any organic radical. The two R'' can be the same or different. Some specific compounds include di-n-butyl-di(benzotriazo-phenoxy-2)-tin; and dimethyl-di-(benzotriazo phenoxy-2-)-silane. These novel compounds can be made by the reaction of benzotriazo phenols with various reactive silane or tin compounds, e.g., halides, etc. The polymers which can be stabilized include polyvinyl chlorides, polyvinylidene chlorides, poly-chloroprenes, chlorinated styrene polymers, chlorinated acrylic polymers, etc.

This specification discloses a novel class of light and heat stabilizers particularly useful with chlorinated polymers. These new compounds have the general formula:
