采用体积排斥色谱法 /示差折光指数 /直角激光光散射 /示差粘度三检测联用技术在 2 5℃的THF中表征了超支化高分子的溶液性质 ;结果表明超支化高分子符合普适标定规律 ,体积排斥色谱法 /示差折光指数 /直角激光光散射 /示差粘度三检测联用技术能解释传统SEC/RI技术不能解释的溶液行为。
The solution properties of hyperbranched polymers were characterized by volume exclusion chromatography / triple refractive index / orthogonal laser light scattering / differential viscosity detection in THF at 25 ℃. The results showed that hyperbranched polymers conformed to universal calibration , Volume Exclusion Chromatography / Refractive Index / Triangle Laser Light Scattering / Differential Viscosity Triple Detection can explain solution behavior that can not be explained by traditional SEC / RI techniques.
