Substituent effect on electrophoretic mobility for a series of poly(N-acryloyl-amino acid)s.

In this study, the electrophoretic mobilities (mu) for a series of poly(N-acryloyl-amino acid)s were determined by capillary zone electrophoresis to investigate the effect of substituent on the electrophoretic behavior of polyelectrolytes. The mu values determined showed a strong correlation with the molar volume of the corresponding amino acids.
