Abstract: Described herein are poly(ether ketone ketone) (“PEKK”) polymers having improved processability. It was surprisingly discovered that by selectively controlling the relative amounts of reactants during the synthesis, PEKK polymers having unexpectedly lower melt viscosities can be obtained. More particularly, by selectively controlling the relative amounts of monomers used to form recurring units of the PEKK polymer, in conjunction with selective control of other reaction components, the resulting PEKK polymers had reduced viscosities, relative to PEKK polymers synthesized by using tradition reaction schemes (“traditional PEKK polymers”). By providing PEKK polymers with lower melt viscosities, the PEKK polymers described herein have improved processability.
