The sulfonate functional (-SO3H) group is attached on the polymer matrix through a chemical link to carbon of the waste polystyrene known as sulfonation process. In general, sulfonating polymer can be achieved by homogeneous reaction in hydrocarbons or chlorinated compounds, where the sulfonation ...
