A molding composition which comprises the following components: a) from 95 to 99.5 parts by weight of a thermoplastic aromatic polyester, b) from 5 to 0.5 parts by weight of a monocarboxylic acid, where the total of the parts by weight of a) and b) is 100; c) from 0.5 to 60% by weight, based on the molding composition, of particulate, lamellar and/or fibrous additives, selected from fillers, pigments, reinforcing materials, additives which give the molding composition antielectrostatic properties or electrical conductivity, nucleating agents, and particulate flame retardants, where the solution viscosity of the resultant polyester molding composition, measured as J value according to DIN 53 728/ISO 1628/Part 5, is in the range from 50 to 80 cm3/g, and the melt index of the molding composition, measured as MVR at 250 DEG C./5 kg is from 12 to 60 cm3/10 min, exhibits a good compromise between flowability and mechanical properties, and can be processed to give injection moldings with sma ll dimensions.
