Abstract: An acrylonitrile/dimethylacrylamide cross-linked polymer could be swollen in different imidazolium ionic liquids. Mechanical compression of the obtained polymer gels inside an NMR tube allowed the measurement of residual dipolar couplings. Conformational analysis of the 1-methyl-3-butyl-imidazolium… read more here.
