SIZE EXCLUSION CHROMATOGRAPHY OF SEMIRIGID POLYIMIDE PRECURSORS.
Abstract
The paper presents SEC results in N-methylpyrrolidone (NMP) obtained when electrostatic interactions are dominant, and when they have been suppressed by addition of a strong electrolyte, i. e. , lithium bromide (LiBr). Results obtained with suppression of the polyelectrolyte effect were in agreement with those obtained by light scattering.
