1. A poly(ether ketone ketone) polymer [PEKKS polymer] comprising
at least one recurring unit (RM*PEKK) of general formula -[Mm-O—]-; and
at least one recurring unit (RP*PEKK) of general formula -[Mp-O—]-;
Mm and Mp are represented by the following formulae, respectively:

OG Complex Work Unit Chemistry
wherein
each of R1 and R2 is independently selected from the group consisting of alkyl, alkenyl, alkynyl, aryl, ether, thioether, carboxylic acid, ester, amide, imide, alkali or alkaline earth metal sulfonate, alkyl sulfonate, alkali or alkaline earth metal phosphonate, alkyl phosphonate, amine and quaternary ammonium; and
each of i and j is independently selected from 0 or an integer from 1 to 4;
said PEKKS polymer being characterized by % [F]>45 (μeq/g)/(g/10 min)0.29 and
T/I ratio greater than 61/39,
wherein
% [F] is the ratio between [F], i.e. the concentration of fluorine end groups in the PEKK polymer measured by 19F-NMR, and MFI, i.e. the melt flow index of the PEKKS polymer determined according to ASTM D1238 at 360° C. with a 8.4 Kg weight to the 0.29 power, and
T/I ratio is the ratio between recurring units (RP*PEKK) and recurring units (RM*PEKK).
