Abstract

The reaction of isotactic polystyrene in the presence of sulfur dioxide and oxygen at constant light intensity was studied as a function of temperature. The gas pressures were kept constant, oxygen was present in excess (150mmHg) and the sulfur dioxide pressure was quite small (0.85mmHg). A general survey was presented previously of polymer-gas reactions (air pollutants) such as NO2 and SO2 1); it was ascertained then, that the presence of SO2 gives rise or enhances chain scission. The effect of NO2 on polystyrene and butyl rubber was studied in detail previously2).
