    Abstract: A method of preparing a poly (ether ketone ketone) consisting essentially of the repeat unit: —Ar—O—Ar—C(═O)—Ar—C(═O)— wherein each Ar is independently an aromatic moiety is provided. The method may comprise the step of polymerising a monomer system in a reaction medium comprising: (a) a Lewis acid; and (b) a controlling agent comprising an aromatic carboxylic acid, an aromatic sulphonic acid, or a derivative thereof.

    Abstract: Filaments are produced from polymers having an inherent viscosity of at least 0.7 measured in concentrated sulfuric acid and containing in the polmer chain at least 50 percent of the repeating units. ##STR1## by melting the polymer and heating the melt to a temperature of from about 20.degree. C. to about 80.degree. C. above the melting point of the polymer, passing the melt through a filter pack having a filtering area of at least about 8 in.sup.2 and a total volume of at least about 1.2 in.sup.3 per pound of polymer extruded per hour, and containing inert, irregularly shaped particles having a mesh size of about 25 to 140 to provide a pressure drop at least about 800 psig., and extruding the melt through spinning openings of desired shape to form filaments. The process is capable of producing fibers and yarns having a dpf of about 15 to 100, a tenacity of about 1 to 2 grams per denier, an elongation at break of about 50 to 160 percent and a modulus of about 20 to 30 grams per denier.
