<p>A polyether ketone, characterized in that it has a primary particle diameter of 50 µm or less; and a method for producing the polyether ketone, characterized in that a polymerization for producing a polyether ketone through the desalting polymerization condensation reaction is carried out in a condition wherein a polymer is precipitated. The polyether ketone has a reduced particle diameter, has an enhanced molecular weight, and is satisfactorily reduced in the content of impurities such as an alkali metal.</p> |
