摘　　要：以马来酸酐、丙烯酰胺等为原料,过硫酸钾-硫代硫酸钠为引发剂,在碱性条件室温聚合合成了高分子共聚物聚丙烯酰胺/马来酰氨基甲酸铵羧酸铵(PAAM/COB)。利用红外光谱对该聚合物结构进行初步确认,并用TiO2超细粉体悬浊液进行分散稳定性能测试。结果表明,PAAM/COB有良好的分散性和稳定性。Using maleic anhydride and acrylamide as raw material, potassium persulfate-sodium thiosulfate as initiator, the copolymer poly-（acrylamide/4-carboxylamino-4-oxo-2-butenate） （PAAM/COB） was synthesized in basic medium at room temperature. The structure of the polymer was confirmed by IR spectrum, and the dispersion stability of PAAM/ COB was examined by measuring sedimentation of super fine TiO2 suspensions. The results showed that this copolymer had good dispersibility and stability.
