Rheological properties of poly(m-phenyleneisophthalamide) in 1-n-butyl-3-methylimidazolium chloride

The steady-state rheological properties of poly (m-phenyleneisophthalamide)(PMIA) in 1-n-butyl-3-methylimidazolium chloride [Bmim]Cl and DMAc/LiCl solutions are presented. The polymer in the concentration range investigated exhibits very different behavior between [Bmim]Cl and DMAc/LiCl solutions. Unlike in DMAc/LiCl solvent, PMIA/[Bmim]Cl solution exhibits maxima in apparent viscosity-concentration plots in the range studied. PMIA shows wormlike chain model when dissolved in DMAc/LiCl while the rodlike chain model in [Bmim]Cl. The different rheological behavior shows polymer-ionic liquids interaction which leads to the supermolecular aggregates in PMIA/[Bmim]Cl solution.
