聚醚砜/酚酞基聚醚砜共混相容性及凝胶特性研究

Miscibility and Coagulation Properties of Polyethersulfone/Phenolphthalein Polyethersulfone Blend Membrane

摘要: 采用混合热焓法和稀溶液粘度法预测了聚醚砜/酚酞基聚醚砜体系相容性,并观察了聚醚砜/酚酞基聚醚砜共混制膜液的凝胶值与共混比的关系.聚醚砜/酚酞基聚醚砜为部分相容体系,其相容性与组成有关.共混制膜液的凝胶值受共混组成的影响,并非纯组分制膜液凝胶值的线性加和.

Abstract: The miscibility and coagulation properties of PES/PES-C blend membrane were studied in this paper. The miscibility was studied by the calculation of the heat of mixing and dilute solution viscometry method. The coagulation property of PES/PES-C blend solu
