Abstract
Acylation of polystyrene with trifluoroacetic anhydride in a solution of aprotonic solvents, namely 1,2-dichloroethane, chlorobenzene at the presence of Lewis acid as catalyst results in obtaining of fluorinated polystyrene, which posses trifluoroacetic fragments in benzoic rings, preferably in position 4. In order to achieve a total substitution of benzene rings in polystyrene macromolecules, the ratio polystyrene : trifluoroacetic anhydride : AlCl3 must be at least 1:10:2.2 mol correspondingly
