  • Process for producing phosphoric acid group containing polyester resins and their use as paint binders
    Patent number: 4450257
    Abstract: A process for producing phosphoric acid group containing polyester resins with substantially total linkage of the phosphoric acid or derivative thereof into the resin system. The process is characterized in that at least 0.1, preferably 0.2 to 1.5, moles/kg of phosphor in the form of a polyphosphoric acid and/or an acidic phosphoric acid ester of mono- or polyhydric alcohol based on the polyacid of the final product is esterified with the other reactants in a 40 to 80 percent by weight of solids containing solution of one or more diluents inert towards the raw materials employed. The reaction is carried to the substantial total linking of the phosphoric acid into the resin system and to an intrinsic viscosity of 3.0 to 25.0 ml/g (DMF, 20.degree. C.).
