Abstract
The interaction of iodine with polystyrene and rubber has been studied spectrophotometrically. Characteristic ``charge‐transfer'' bands were observed, and interpreted quantitatively in terms of complex formation. The equilibrium constants and ``molar'' extinction coefficients of the polymer‐iodine complexes are similar to those for the iodine complexes of analogous simple aromatic and olefinic molecules. Approximately half of the iodine in solid solution in polystyrene seems to be involved in complex formation. Polystyrene is soluble in strong alcoholic solutions of silver perchlorate, and the absorption spectrum of the solution indicates complex formation.Keywords
