In this paper, the rheologic properties of polysulfone ( PS)/ dimethyl acetamide ( DMAc)/ polyethylene glycol ( PEG) hollow fiber casting solution were studied with capillary rheometer.
本文用气压式毛细管流变仪对聚砜/二甲基乙酰胺/聚乙二醇中空纤维铸膜液的流变性能进行了分析与讨论。
The miscibility of PVDF blends in N, N-dimethyl acetamide ( DMAC) were characterized by solubility parameter, glass transition temperature and viscosity, etc. The result showed PVDF/ PMMA blend system is completely miscible while PVDF/ PSA blend system is partially miscible.
利用溶解度参数法、绝对粘度法、玻璃化转变温度法等方法确定了共混体系的相容性:PVDF/PMMA共混体系为完全相容体系,PVDF/PSA共混体系为部分相容体系。
