An aromatic polyester shaped article, for example, a fiber, a film or a sheet, having excellent hydrophilic characteristics and a durable antistatic property, sweat-absorbing property and soil-releasing property, is prepared from an aromatic polyester composition comprising (a) 100 parts by weight of an aromatic polyester resin, (b) 0.2 to 30 parts by weight a water-insoluble polyoxyethylene type polyether represented by the formula (I): Z-[(CH2CH2O)l-(R1O)m-R2]k (I) wherein Z is a residue of an organic compound having 1 to 6 active hydrogen atoms and a molecular weight of 300 or less, R1 is an unsubstituted or substituted alkylene group having at least 6 carbon atoms, R2 is H, a monovalent hydrocarbon group having 1 to 40 carbon atoms, or a monovalent acyl group having 2 to 40 carbon atoms, k is 1 to 6, l satisfies the relationship: kxl>/=70 and m is 1 or more, and having a number average molecular weight of 5000 to 16000, said R1, R2, l and m in the formula (I) satisfying the following relationships: when k=1, <IMAGE> and when k=2 to 6, <IMAGE> wherein [M(R1O)] is a molecular weight of the R1O and [M(R2)] is a molecular weight of the R2. |
