| Abstract:In this study, polyamine type emulsifier (PDMDAAC) with high cationic charge density was synthesized and the effects of reaction temperature, reaction time, monomers ratio, initiator dosage and pH value on the viscosity-average molecular weight and charge density of the product were investigated. The synthesized PDMDAAC was used to emulsify AKD, the effects of synthesis conditions of emulsifier on the stability of emulsion was studied. The results showed that the optimized reaction temperature was 80 ℃, the reaction time was 3 h, the ratio of dimethyl diallyl ammonium monomers and diallylamine was 100∶4, the dosage of initiator-ammonium persulfate was 0.10%, pH value was 5. |
