| Abstract: | Summary The rheological behavior of poly(m-phenyleneisophthalamide) (PMIA) in 1-n-butyl-3-methylimidazolium chloride (Bmim]Cl, ionic
liquid) has been investigated. The polymer in the concentration range 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 steady-state
rheological behavior. The different rheological behavior shows the interaction between macromolecule and IL which leading
the supermolecular aggregates in PMIA/Bmim]Cl solution. |
