摘要
以N,N-二甲基甲酰胺(DMF)为溶剂,采用DSV研究了聚氨酯/聚砜(TPU/PSF)和聚氨酯/聚甲基丙烯酸甲酯(TPU/PMMA)两种共混体系的相容性。运用μ和α判据分别对TPU/PSF和TPU/PMMA两共混体系的相容性进行了判断,结论完全一致,TPU/PSF体系相容,而TPU/PMMA体系不相容。
The miscibilities of thermoplastic polyurethane elastomer /polysulfone (TPU/PSF) and thermoplastic polyurethane elastomer / polymethylmethacrylate (TPU/PMMA) polyblends in DMF solvent are determined by the measurement of DSV, Both α and μ criteria are used to study the miscibilities of TPU/PSF and TPU/ PMMA polyblends, respectively. The results show that the μ criterion is consistent with the α criterion. TPU/PSF polyblend is miscible, but TPU/PMMA is immiscible.
