A dispersant which is a phosphate ester of a polymer which contains at least one ether group and a poly(oxyalkylenecarbonyl) chain (POAC chain) derivable from two or more different hydroxycarboxyl acids or lactones thereof. Also disclosed is the use of the dispersants in paints and printing inks includin g millbases. The preferred dispersants are phosphate esters of an alkyl end- capped poly(oxyalkylenecarbonyl) chain alcohol where the POAC chain is deriv ed from .epsilon.-caprolactone and .delta.-valerolactone and the alkyl group is derived from a monohydroxypolyalkyleneglycol.
