| 摘 要： | 超支化聚缩水甘油醚(HPG)、丙烯酰胺(AM)在铈盐-羟基引发体系下发生自由基聚合,得到了高度支化的水溶性超支化聚丙烯酰胺HPG-star-PAM,采用傅里叶变换红外光谱(FT-IR)、核磁共振氢谱(1 H-NMR)及热失重分析(TGA)对聚合物结构和组成进行了表征,使用乌式黏度计测定了聚合物的特性黏数,并使用旋转流变仪研究了其流变特性,结果表明高度支化的聚丙烯酰胺样品具有优异的抗剪切性能.

| Abstract: | A novel water-soluble highly branched polyacrylamide（HPG-star-PAM）was synthesized from hyperbranched polyglycerol（HPG）and acrylamide（AM）by free radical polymerization via cerate-hydroxyl initiator system.Polymer compositions and structures were characterized by Fourier transform infrared spectrum（FT-IR）,^1H-nuclear magnetic resonance（^1H-NMR）and thermo gravimetric analysis（TGA）.Intrinsic viscosity was measured by Ubbelohde viscometer,and rheological behavior was tested by rotational rheometer.The results showed that the highly branched polyacrylamide has a good shear resistance. |
