The rheological behavior of poly(m-phenyleneisophthalamide) (PMIA) in 1-n-butyl-3-methyrimidazolium chloride ([Bmim]Cl,ionic liquid) has been investigated.The polymer in the concentration range of 2-20wt.% investigated exhibits very different behavior between [Bmim]Cl and DMAc/LiCl solvent.Unlike in DMAc/LiCl solvent,PMIA/[Bmim]Cl solution exhibits maxima in apparent viscosity-concentration plots in the range studied.The complex viscosity-frequency behavior of the PMIA/[Bmim]Cl solutions is similar to that of steady-state rheological behavior.The different rheological behavior shows the interaction between macromolecule and IL which is leading to the supermolecular aggregates in PMIA/[Bmim]Cl solution.
