Abstract: A stable cationic polyacrylamide (PAM-DMC) emulsion is prepared through a kind of dispersion polymerization technology by using acrylamide (AM) and methacryloyloxyethyl trimethyl ammonium chloride (DMC) as monomers,diethylene glycol butyl ether as dispersant,and ammonium persulfate-sodium bisulfite REDOX system as initiator.The structure of PAM-DMC is confirmed by means of FT-IR,XRD,TG and DTA.PAM-DMC emulsion is analyzed by TEM,and its emulsion stability and flocculation performance are also analyzed and determined.The results show that the copolymer PAM-DMC is amorphous and has a good thermal stability.Its dynamic instability index (TSI) is less than 0.13 and it is spherical or ellipsoidal particles with a diameter of 100-500 nm and an average particle size of 198.6 nm.The dissolution time will be 156 min,the cationic degree can reach 7.59% and the characteristic viscosity will be 498.24 Pa·s when the molecular weight is 1.85×106 and the flocculation efficiency of PAM-DMC reaches the maximum.
