Abstract
Physical and chemical properties of LPPS in aqueous solutions were studied. Hydrodynamic characteristics of LPPS depend upon the input concentration and method of solution preparation. Equation parameters for the relationship between [eta] and M omega were determined, and it was found that LPPS behavior in solution can be determined by the equation: [eta] = 5.5.10(-4).M0.57. In aqueous solutions complex macromolecules form compact particles ranging from 8 to 14 nm in size.
摘要
研究了低聚苯硫醚（LPPS）在水溶液中的物理和化学性质。LPPS的流体动力学特性取决于输入浓度和溶液制备方法。确定了特性黏度[η]与分子量Mω之间关系的方程参数，发现溶液中LPPS的行为可用以下方程确定：[η]=5.5×10⁻⁴·M⁰·⁵⁷。在水溶液中，复杂的大分子形成尺寸范围为8至14纳米的致密颗粒。
