摘要
本文研究了添加脲（添加量为丙烯酞胺的０．０６３到０．２００质量比）对丙烯酰胺聚合的影响。脲的加入能取代丙烯酞胺的双分于氢键缔合，使聚丙烯酰胺的水溶性速度提高，玻璃化温度下降。用红外光谱分析和差热分析的结构分析证实了上述机理。
This paper studied the effects of urea concentration from 0. 063 to 0. 200(g/g from AM )on acrylamide polymerization. Urea can replace the hydrogen bond of polyacry- lamide,and then increased the rate of dissolve of polyacrylamide in water,and decreased the Tg of polyacrylamide product . The spectums of FTIR and DSC demonstrated this conclusions.
