摘要
采用新型氧化-还原体系,以丙烯酰胺(AM)和丙烯酸(AA)为单体共聚得到阴离子聚丙烯酰胺(HPAM)。研究了EDTA用量、反应温度等对HPAM制备的影响。结果表明:EDTA用量、反应温度等直接影响到HPAM的分子量高低与溶解性好坏。用傅立叶红外光谱仪对一定工艺条件下所得产物进行表征,证明可得到分子量高且溶解性能好的HPAM。
Anion polyacrylamide was synthesized with acrylamide and prownoic acid as the monomers with a new system. The efect of pH value, reaction tempreture to HPAM were studied. The results showed that these factors influenced the molecular weight and dissolution ability directly. And infra - red spectra apparatu＇s types proved it.
