摘　　要：　合成了造纸填料用分散剂,讨论了马来酸酐与丙烯酸比例、引发剂体系种类对树脂粘度及分散性的影响。结果表明:丙烯酸与马来酸酐的摩尔比为1.5时分散碳酸钙浆效果较好,而纯丙烯酸的分散性最佳;引发体系以过硫酸铵 亚硫酸氢钠 硫酸亚铁为优,亚硫酸氢钠占单体质量的13.5%,硫酸亚铁占单体质量的0.0067%。通过优化确定了合成的最优条件。Dispersant for paper filling was synthesized.Effects of acrylic acid/maleic anhydride ratio and type of initiating agent on rasin viscosity and dispersion were discussed.Dispersant from acrylic acid/maleic anhydride molar ratio 1.5 can well disperse calcium carbonate paste,while polyacryllic acid disperses calcium carbonate paste best.Ammonium persulfateferrous sulfitesodium bisulfite is the best initiating agent.Sodium bisulfite is 13.5% and ferrous sulfite is 0.006 7% of monomer.Optimal conditions were determined.
