Synthesis , flocculation properties ,hydrophobic organic polymer P(AM-DM-DMC12)

A new modified hydrophobic organic polymer P(AM-DM-DMC12) was synthesized by free radical polymerization of three monomers in aqueous solution using REDOX initiator system. Its structure was characterized by infrared spectroscopy, and the effect of reaction conditions on the product was studied, and the flocculation performance and mechanism were discussed with the aim of wastewater turbidity and COD removal rate. The results showed that the synthesized compounds accorded with the target structure, and the optimum synthetic conditions were as follows: total mass fraction of monomer was 35%, the mass fraction of redox initiator was 0.06%. Moreover, the flocculation effect of P (AM-DM-DMC12) is obviously better than that of PAM, and it has the advantages of short flocculation time, low dosage and wide application range of pH, and has good industrial application value and prospect. <br>
