NOVELTY - Polymeric composition comprises a copolymer having two separate recurring units, a first recurring unit containing 1-methyl-3-(4-(4-methyl-benzoyl)-phenyl)-1,3-dihydro-benzoimidazol-2-one containing compound (I) and a second recurring unit containing (4-(4-hydroxy-phenoxy)-phenyl)-phenyl-methanone containing compound (II), where the value of the subscript x is 2-5000 subject to the limitation that the value of the subscript y is 2-5000, the ratio of x:y is (1:99-9.5):91.5, the polymeric composition is semicrystalline having an inherent solution viscosity of greater than 0.3 dL/g, a Tg greater than 150degrees Celsius, a Tc less than 280degrees Celsius, a Tm less than 340degrees Celsius, and an enthalpy of melting endotherm (DeltaHm) greater than 10 J/g and less than 55 J/g and where the semicrystalline copolymer crystallizes from a melt at a cooling rate of 5-200degrees Celsius/minute. USE - The composition is useful in an article of manufacture and for providing advantageous semicrystalline poly(aryl ether ketone) materials for use in additive manufacturing, composite materials, coating, injection molding, extrusion, blow molding, rotational molding and thermoforming. ADVANTAGE - The composition meets the need for new semicrystalline poly(aryl ether ketone) polymers that can be reliably processed at low temperatures, and which retain their technical properties, notably their chemical resistance and mechanical properties (when compared with conventional poly(ether ether ketone) polymer and poly(ether ketone) polymer) and has lower melting temperature, lower crystallization temperature, and higher glass transition temperature.
