| Abstract: | The copolymers of acrylamide and styrene were prepared by emulsifier-free copolymerization. The mass fraction of acrylamide in the copolymer was 0.40 - 0.73. The emulsion was modified into cationic polymer by Hofmann reaction. The diameter of the microparticles in the emulsion with the mass fraction of 0.73 was 85 nm, conversion fields of amino groups and caxboxyl groups were 69.5% and 6.4%, respectively. |
| Keywords: | cationic polyacrylamide emulsion emulsifier-free copolymefization Hofmann reaction |
