摘要：

Surface properties of two polyethers containing pyridine and pyrazine units, respectively, were compared with polysulfone. The polymers were investigated by inverse gas chromatography. The dispersive contributions of the surface free energy and the K-A and K-B parameters expressing the ability of the stationary phase to act as Lewis acid or Lewis base were calculated. It was shown that the polymer with pyridine units possessed extraordinarily high K-B values whereas the polysulfone showed amphoteric behaviour with predominant Lewis basicity.
