Abstract

Organo-tin compounds, added to PVC for stabilization properties, will immediately react with chlorine atoms or HC1 and will form mono- or dichloride organo-tin compounds. In a short time migration test (2 hours at 70 degrees C), using heptane as the contacting liquid, mass spectrometric measurement revealed such chlorinated organo-tin and polymeric tin compounds. Gamma irradiation stimulated the formation of a heptane soluble, non-volatile Sn compound with a high migration tendency. Possible degradation mechanisms or the organo-tin stabilizer under the influence of gamma irradiation are proposed.
