    Abstract: LINEAR POLYESTERS OF A PHOSPHORUS-CONTAINING ACID AND A DIOL AS ILLUSTRATED BY A POLYESTER HAVING REPETITIVE UNITS OF THE FORMULA:

    -X-P(=X)(-Z)-B-

    WHERE X IS OXYGEN OR SULFUR; B IS A DIOL RESIDUE; Z IS HYDROGEN IN THE CASE OF A PHOSPHITE ESTER I.E. H; A HYDROCARBON OR A SUBSTITUTED HYDROCARBON GROUP IN THE CASE OF A PHOSPHONATE ESTER I.E. R; AN OXYHYDROCARBON OR A SUBSTITUTED OXYHYDROCARBON GROUP IN THE CASE OF A PHOSPHATE ESTER I.E. -OR;A THIOHYDROCARBON OR A SUBSTITUTED THIOHYDROCARBON GROUP IN THE CASE OF THIOPHOSPHATE ESTER I.E. -SR. THE PREFERRED POLYESTER HAS REPEATING UNITS OF THE FORMULA

    -O-P(=O)(-Z)-(OA)N-

    WHERE OA IS THE RESIDUE OF AN ALKYLENE OXIDE OR A SUBSTITUTED ALKYLENE OXIDE; N IS AN INTEGER, FOR EXAMPLE 1-300 OR MORE, SUCH AS ABOUT 2-250, FOR EXAMPLE ABOUT 3-200, BUT ADVANTAGEOUSLY ABOUT 5-130, AND Z IS HYDROGEN, A SUBSTITUTED GROUP (R), FOR EXAMPLE, ALKYL, ARYL, CYCLOALKYL, ALKARYL, ARALKYL, HETEROCYCLIC INCLUDING SUBSTITUTED DERIVATIVES THEREOF, ETC.; ALKOXY OR ARYLOXY GROUP (OR) FOR EXAMPLE METHOXY, PROPOXY, ISOPROPOXY, 2-ETHYLHEXOXY, ETC., PHENOXY, ETC. THESE POLYESTERS ARE EMPLOYED AS DEMULSIFIERS AS WELL AS FOR OTHER USES.

    Abstract: LINEAR POLYESTER OF A PHOSPHORUS-CONTAINING ACID AND A DOIL AS ILLUSTRATED BY A POLYESTER HAVING REPETITIVE UNITS OF THE FORMULA:

    -X-P(=X)(-Z)-B-

    WHERE X IS OXYGEN OR SULFUR; B IS A DIOL RESIDUE; Z IS HYDROGEN IN THE CASE OF A PHOSPHITE ESTER I.E. H; A HYDROCARBON OR A SUBSTITUTED HYDROCARBON GROUP IN THE CASE OF A PHOSPHONATE ESTER E.E. R; AN OXYHYDROCARBON OR A SUBSTITUTED OXYHYDROCARBON GROUP IN THE CASE OF THE THIOPHOSPHAGE ESTER I.E. - SR. THE PREFERRED POLYESTER HAS REPEATING UNITS OF THE FORMULA

    -O-P(=O)(-Z)-(O-A)N-

    WHERE OA IS THE RESIDUE OF AN ALKYLENE OXIDE OR A SUBSTITUTED ALKYLENE OXIDE; N IS AN INTEGER, FOR EXAMPLE 1-300 OR MORE, SUCH AS ABOUT 2-250, FOR EXAMPLE ABOUT 3-200, BUT ADVANTAGEOUSLY ABOUT 5-130, AND Z IS HYDROGEN, A SUBSTITUTED GROUP (R), FOR EXAMPLE, ALKYL, ARYL, CYCLOALKYL, ALKARYL, ARALKYL, HETEROCYCLIC, INCLUDING SUBSTITUTED DERIVATIVES THEREOF, ETC.; ALKOXY OR ARYLOXY GROUP (OR) FOR EXAMPLE METHOXY, PROPOXY, ISOPROPOXY, 2-ETHYLEHEXOY, ETC., PHENOXY, ETC.
