  • Patent number: 4401804
    Abstract: A process is provided for deactivation of catalyst residues in polyester compositions. The polyester compositions are provided by polymerizing diols and diacids, or mixtures of such diols and diacids, to form polyester compositions. The polymerization is carried out in the presence of a polymerization catalyst that leaves traces of such catalyst residues in the polyester composition. These catalyst residues can adversely affect the further processing and end use of the polyester composition. The present process provides deactivation of the catalyst residues by the use of a combination of a mono- or dihydrogen phosphonate or mono-, di-, or trihydrogen phosphate compound and a di- or triester phosphonate compound or a phosphite compound.
