Summary

The synthesis of the copolymer styrene m, p-hydroxystyrene has been carried out by chemical modification of polystyrene. The initial polystyrene has been lithiated by the complex of sec-butyllithium with N,N,N′,N′-tetramethylethylenediamine in cyclohexane and hexane. The lithiated sites have been quenched with oxygen. From the physicochemical characterization we have observed that the initial polystyrene is not degraded and that the oxidation reaction is quantitative. This reaction yields a styrene m,p-hydroxystyrene copolymer. The hydroxy groups are located in the meta(2/3) and para-positions of the aromatic ring.
