Two CF 3 ‐terminated polymers were synthesized by polymer analogous reactions in order to study the effect of the terminal CF 3 groups on their surface properties. ESCA and NEXAFS showed that they contain highly ordered side chains oriented perpendicularly to the polymer surface. The CF 3 ‐terminated polymers showed enhanced wettability by polar solvents as compared to the corresponding CH 3 ‐terminated polymers, while the wettability by non‐polar dodecane showed the opposite trend. This was attributed to specific interactions between the oriented surface dipoles of the CF 3 ‐terminated surfaces and the polar solvents. Thus, terminal CF 3 groups in a polymer can increase its surface polarity.
