摘　　要：通过电导率和透光率来优化反相微乳液制备两性聚丙烯酰胺的合成工艺,得到最佳合成条件为:EDTA加入量0.5%(对单体质量)、搅拌速度为300 r/min、乳化剂用量为18.61%(对乳液总质量)、反应时间为3 h、引发剂用量为0.5%(对单体质量)、单体质量分数为50%(对水相质量)、反应温度为25℃;并检测了在此优化条件下制备的两性聚丙烯酰胺的助留助滤性能,结果表明,该两性聚丙烯酰胺具有较好的助留助滤性能,当加入量为0.08%(对绝干浆)时,纸料留着率提高了8.9%,打浆度降低了6.1°SR。The inverse microemulsion polymerization process of amphoteric polyacrylamide was optimized by transmittance and the conductance ratio measurement. Polyacrylamide with optimum retention and drainage effects can be obtained when EDTA dosage, stirring speed, emulsifier addition level, reaction time, initiator dosage, monomer mess ratio and reaction temperature were 0.5% , 300 r/min, 18.61% , 3 h, 0.5% , 50% and 25 ℃, respectively. When the addition level of amphoteric polyacrylamide is 0.08% , furnish retention was increased by 8.9% while the beating degree was decreased by 6.1 °SR.
