NOVELTY - Amorphous fluorinated polymer comprising at least 20 mole% of recurring units derived from at least one fluorinated monomer providing alicyclic structures in the polymer main chain (fluorinated monomer), 1.5-7.5 mole% of recurring units derived from at least one fluorinated monomer comprising sulfur oxide functional groups (Ia) (fluorinated functional monomer), and optionally recurring units derived from at least one ethylenically unsaturated fluorinated monomer present up to 100 mole%, is new.    USE - The amorphous fluorinated polymer is useful: for the preparation of anti-reflective and anti-glare films or coatings, protective transparent films or coatings, or dielectric films or coatings; and in a film or coating which is useful in the article comprising corrective lenses, camera lens elements, displays, telescopes, solar panels and components of organic LED and organic FET displays (all claimed).    ADVANTAGE - The amorphous fluorinated polymer exhibits: improved adhesion to glass and good light transmission properties; and at least 3 times higher peeling strength from a glass substrate when compared to conventional polymer which does not contain the functional groups (Ia).    DETAILED DESCRIPTION - Amorphous fluorinated polymer comprising at least 20 mole% of recurring units derived from at least one fluorinated monomer providing alicyclic structures in the polymer main chain (fluorinated monomer), 1.5-7.5 mole% of recurring units derived from at least one fluorinated monomer comprising sulfur oxide functional groups of formula (Ia) (fluorinated functional monomer), and optionally recurring units derived from at least one ethylenically unsaturated fluorinated monomer present up to 100 mole%, is new.    X1a = halo or -O-M1a+; and    M1a+ = H+, NH4+, K+, Li+ and/or Na+.    INDEPENDENT CLAIMS are also included for:    (1) a film or a coating comprising the amorphous fluorinated polymer;    (2) an article comprising the film or coating; and    (3) preparing the film or the coating comprising casting a solution of the amorphous fluorinated polymer in a fluorinated solvent.
