摘要
合成了一种新型的两亲性共聚物（丙烯酰胺/醋酸乙烯酯/丙烯酸丁酯,AM/VAc/BA）,探讨了在该共聚物合成过程中AM用量和VAc与BA的配比对其表面张力、离心稳定性、乳化性及发泡力的影响,并对该三元共聚物P（AM/VAc/BA）的结构进行表征。结果表明,傅立叶红外光谱（FT-IR）分析在1 680 cm^-1-1 620 cm^-1处无C=C伸缩振动吸收峰出现,说明体系反应较彻底;差示扫描量热（DSC）分析得共聚物的玻璃化转变温度为37.6℃。
An amphiphilic polymer, acryl amide （AM）/vinyl acetate （VAc）/butyl acrylate （BA） was synthesized with the effects of amount of AM as well as the ratio between VAc and BA on surface tension, stability against centrifugation, emulsifying power and foaming power of the product examined. In addition, the structure of the ternary co - polymer, AM/ VAc/BA was characterized by Fourier transform infrared spectroscopy （FT- IR） and differential scanning calorimetry （DSC）. In the FT -IR spectrum, there is no C = C stretching vibration absorption peak at 1 680 cm^- 1-1 620 cm^- 1. From DSC analysis, the glass transition temperature is identified as 37.6 ℃. Such analytical results indicated that the polymerization reaction is complete.
