  A cationic dye-dyeable polyester resin composition comprising a polyalkylene terephthalate containing metal sulfonate groups and a melt viscosity depressant, selected from the group of particular bisphenol ethers or pyromelistic acid-bis (N-alkyl-imides). Addition of the melt viscosity depressant to the polyester resin reduces the melt viscosity without decreasing the intrinsic viscosity of the resin thereby making it melt-spinnable. A cationic dye-dyeable polyester fiber with high strength can be obtained from the polyester resin composition.

  A new melt viscosity depressant for a polyester resin having a structure of an aromatic carbonyl compound is disclosed. Addition of the melt viscosity depressant to a polyester resin reduces the melt viscosity of the resin remarkably, thereby facilitating mold processing and melt-spinning of the polyester resin composition, from which high strength polyester molding products and polyester fibers can be obtained.
