摘要
用高效体积排斥色谱法、小角激光光散射法和稀溶液粘度法研究了聚砜和聚苯乙烯在四氢呋喃中的稀溶液性质。结果表明,此两种聚合物遵从共同的流体力学体积普适标定关系。订定了聚苯乙烯在四氢呋喃中25℃时的Mark-Houwink方程。用Stockmayer-Fixman理论估算了聚苯乙烯的无扰尺寸。
This work have researched the dilute solution properties of polysulphone andpolystyrene in tetrahydrofuran by high performance size exclusion chromatography.low angle laser light scattering and viscometry. The results show that both poly- mers conform to identical hydrodynamic volume universal calibration curve. At thesame time. the Mark-Houwink equation of polystyrene in THF at 25℃ has beenstipulated. And the value of unperturbed dimension of polystyrene has been estima-ted by applying the theory of Stockmayer and Fixman.
