【摘要】 目的　通过对医用聚丙烯酰胺水凝胶 (Amazingel)化学结构分析 ,C、H、O、N元素之间的分子链、交联、支链离解等结构的变化。方法　采用红外吸收光谱KBR压片法。结果　KBR压片法红外吸收光谱图中有酰胺基、仲酰胺、亚甲基的特征峰与标准聚丙烯酰胺图谱基本相同。结论　该材料属高分子三维网状结构的聚合物 ,没有发现有链和支链分子间的离解 ,其化学结构稳定更多还原

【Abstract】 Objective To observe the structural change of molecule chain, interlinkage and branch chain dissociation between elements of C, H, O, N with chemical structure analysis on medical polyacrylamide hydrogel(Amazingel). Methods Use inftared absorption spectrum KBR compression method. Results In the picture of infrared absorption spectrum, we can see characteristic peaks of amide, secondary amide and methene which are basically as same as standard polyacrylamdie atlas (pattern). Conclusion This material belongs to high polymer with 3D network structure. Dissociation between chain and branch chain molecules are not found and its chemical structure is stable.更多还原
