摘　　要：以壳聚糖(CTS)、衣康酸(IA)和马来酸酐(MA)为原料,以醋酸为溶剂、(NH_4)_2S_2O_8为引发剂,合成了CTS-IA-MA三元接枝共聚物。聚合反应的最佳条件为:反应温度90℃,n(CTS):n(IA):n(MA)=1:1.5:1.0,引发剂质量分数0.35%,反应时间5 h。通过傅立叶变换红外光谱(FTIR)表征,所得产物为CTS-IA-MA接枝共聚物。三元接枝共聚物质量浓度为50 mg/L、水样pH为中性或弱酸性时三元接枝共聚物对CaCO_3的阻垢效果较好。Using chitosan（CTS）,itaconic acid（IA）,maleic anhydride（MA） as raw materials, acetic acid as solvent and（NH4）2S2O8 as initiator,the ternary graft copolymer CTS-IA-MA was synthesized.The optimum polymerization conditions are as follows:reaction temperature 90℃, n（CTS）:n（IA）:n（MA）=1.0:1.5:1.0,initiator mass fraction 0.35%,reaction time 5 h.The product is characterized as CTS-IA-MA graft copolymer by FTIR.When the mass concentration of the ternary graft copolymer is 50 mg/L,the water pH is neutral or subacid,the ternary graft copolymer has a good effect on CaCO3 scale inhibition.
