A classification of dispersed structures is presented for the polysulfone (PSF) + short glass fibers (GF) dispersed system, and their relationship with generalized parameter Θ and the content of dispersed filler is shown. A relationship is established between generalized structure parameter Θ and rheological properties of glass-filled PCMs based on PSF. It has been shown that the change in the parameters of the structure from a diluted to a medium-filled system leads to the formation of a quasi-continuous framework of dispersed particles at Θ = 0.45 parts by volume in dispersed-filled polymer composite materials (DFPCMs), while the viscosity of PSF-190 + GF melts increases by around three or four times in the processing temperature range from 290 to 340°C. It has been established that the introduction of glass fiber into PSF has practically no effect on the thermal stability time of polysulfone melts. Optimal temperature conditions for their processing into products by injection molding are proposed for DFPCMs based on PSF-190 + GF with different types of structures, viscosities, and thermal stability times.

分散结构的广义参数对玻纤聚砜流变性能的影响

给出了聚砜（PSF）+短玻璃纤维（GF）分散体系的分散结构分类，并显示了它们与广义参数Θ和分散填料含量的关系。建立了广义结构参数 Θ 与基于 PSF 的玻璃填充 PCM 的流变特性之间的关系。已经表明，结构参数从稀释到中等填充系统的变化导致在 Θ = 0.45 体积份分散填充聚合物复合材料中形成分散颗粒的准连续框架（ DFPCMs)，而 PSF-190 + GF 熔体的粘度在 290 至 340°C 的加工温度范围内增加了大约三到四倍。已经确定，将玻璃纤维引入 PSF 中实际上对聚砜熔体的热稳定时间没有影响。针对基于 PSF-190 + GF 的具有不同类型结构、粘度和热稳定性时间的 DFPCM 提出了通过注塑成型加工成产品的最佳温度条件。
