The phosphate is drawn into AA/AMPS/MAn trinary copolymer with water as solvent, sodium dihydrogen phosphite and persulfate ammonium as initiator. Thereby a good synthesis function and low phosphate content water treatment agent is obtained. The synthesis function, proportion of monomers, dosage of initiator and the relation between temperature and time of the reaction are inspected. The optimum technological condition to synthesize this copolymer:m(2-acrylamido-2-methyl propanesulfonic acid):m(acrylic acid):m(maleic anhydride) = 1:4:5, w(sodium dihydrogen phosphite) = 4.5%, w(persulfate ammonium) = 3%. The reaction temperature is 95 ~ 98℃,time of reaction is 4 h.
