Abstract: Described is a process for producing linear polyesters of improved whiteness and reduced yellowness by esterification of aromatic dicarboxylic acids or transesterification of their bis(lower alkyl) esters with or without aliphatic dicarboxylic acids with diols to form bisdiol esters and their oligomers and further condensation of these preproducts to spinnable polyesters, which comprises adding to the esterification, transesterification or polycondensation hatch from 0.5 to 15% by weight of phosphorus-containing modifiers and conducting the polycondensation initially in the melt to an IV from 0.4 to 0.55 dl/g and thereafter in solid phase to an IV from 0.62 to 0.72, the indicated IV values being measured at 25.degree. C. in dichloroacetic acid.
