Popis:	Poly-4,4′-diphenylphthaleinterephthalamide has been fractionated into 19 fractions in the system DMF (solvent)-ethanol (sedimentator), using the successive sedimentations method. A special method for determining sedimentation boundary dispersion was used to characterize the polydispersity of the fractions. It was found that for most of the fractions Mz/Mw
