Abstract
Polystyrene and poly-β,β-dideuterostyrene have been photo-chlorinated in solution in carbon tetrachloride. The products have been examined by i.r., 220 MHz NMR and laser Raman spectroscopy. For chlorination at 13°, approximately equal numbers of chlorine atoms are introduced at α- and β-sites along the chain; in the later stages of reaction, there is appreciable addition of chlorine to the rings. The photo-chlorination is accompanied by degradation of the polymer; the average number of scissions per polymer molecule is better correlated with the amount of chlorine introduced into the main chain than with the total chlorine content of the polymer.
