It is provided a process for modifying an aromatic polyether backbone for obtaining a modified polyether comprising the steps of: a) providing the at least one aromatic polyether to be modified in dissolved state in an inert organic solvent, b) adding at least one modification reagent, c) adding at least one catalyst, d) carrying out the process until a desired degree of functionalization of said aromatic polyether backbone is reached, e) recovery of the modified aromatic polyether.

Described herein are articles coated with one or more polyelectrolyte complexes. The polyelectrolyte complexes have a high glass transition temperature when the coating is contacted with an aqueous medium. In one aspect, the coating has a glass transition temperature of at least 45? C. when in contact with an aqueous medium, which makes the coatings described herein as glassy. The coating compositions described herein are effective in reducing adhesion of organisms on the surface of the coated article, which makes the coatings an effective antifouling coating.
