用光散射、速度沉降和粘度法研究了宽分子量范围的窄分布聚苯乙烯样品在热力学半良溶剂丁酮中的稀溶液行为,与聚苯乙烯在θ溶剂和良溶剂中的文献数据相比较,讨论了聚苯乙烯的稀溶液性质.
The light scattering, velocity sedimentation and viscosity method were used to investigate the dilute solution behavior of a narrow molecular weight range of narrow polystyrene samples in the thermodynamic semipermeable butanone. Compared with the literature data of polystyrene in θ solvent and good solvent, The dilute solution properties of polystyrene are discussed.
