Studies are carried out on the feasibility of two kinds of sulfates as the dispersion medium of CPAM dispersion polymerization,as well as the impact of different kinds of dispersants on CPAM dispersion polymerization. As the solubility fluctuates sharply with the change of temperature,sodium sulfate is not suitable for being used as the dispersion medium for CPAM dispersion polymerization. Non-ionic dispersants,due to their poor solubility in saline medium,are not suitable for being used as the dispersant,either. Therefore,ammonium sulfate and PDMDAAC are selected as the dispersion medium and dispersant respectively,in order to obtain products with preferable fluidness. Studies show that, for ammonium sulfate,the optimum dosage is 27%-29%,and PDMDAAC is 10%-18%.
