    Abstract: Disclosed is a method for producing a phosphate polymer wherein a monomer 1 represented by the general formula (1) below, a monomer 2 represented by the general formula (2) below and a monomer 3 represented by the general formula (3) below are copolymerized in a polymerization solvent having a dissolved oxygen concentration at 25°C of 0.01-4.0 mg/kg at a pH of 7 or less. Also disclosed is a method for producing a phosphate polymer wherein the monomers 1, 2 and 3 are copolymerized in the presence of a phosphonic acid chelating agent at a pH of 7 or less. Further disclosed is a method for producing a phosphate polymer using a mixed solution containing the monomers 1, 2 and 3, wherein the mixed solution is obtained by mixing the monomers 1-3 at a temperature of 10-50°C and polymerization is started within 72 hours after mixing of the monomers 1-3, while keeping the temperature of the mixed solution within the range of 10-50°C until the polymerization is started. (In the formula (1), R 1 and R 2 respectively represent a hydrogen atom or a methyl group; and R 3 represents a hydrogen atom or -COO(AO) n X wherein AO represents an oxyalkylene group having 2-4 carbon atoms or an oxystyrene group, n represents a number of 3-200 which is an average mole number of added AO, and X represents a hydrogen atom or an alkyl group having 1-18 carbon atoms.). (In the formula (2), R 4 represents a hydrogen atom or a methyl group; R 5 represents an alkylene group having 2-12 carbon atoms; m1 represents a number of 1-30; and M represents a hydrogen atom, an alkali metal or an alkaline earth metal.). (In the formula (3), R 6 and R 8 respectively represent a hydrogen atom or a methyl group; R 7 and R 9 respectively represent an alkylene group having 2-12 carbon atoms; m2 and m3 respectively represent a number of 1-30; and M represents a hydrogen atom, an alkali metal or an alkaline earth metal.)
