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 materials and potassium persulfate-sodium thiosulfate as initiator, the polymer copolymer polyacrylamide / ammonium maleatecarboxylate (PAAM) was synthesized at room temperature under alkaline conditions / COB). The structure of the polymer was preliminarily confirmed by infrared spectroscopy and the dispersion stability was tested by using TiO2 ultrafine powder suspension. The results show that, PAAM / COB has good dispersion and stability.
