A method of inhibiting silica/silicate scale in aqueous systems is disclosed which comprises the addition to an aqueous system of a scale inhibiting amount of an ester of (A) a carboxylic acid functional polymer obtained by polymerizing an ethylenically unsaturated carboxylic monomer or copolymerizing the ethylenically unsaturated carboxylic monomer with one or more additional ethylenically unsaturated monomers and (B) a hydroxyl functional polyether obtained by reacting an alkyl alcohol with an alkylene oxide.
