The density values of polyetherimide solutions in N-methyl-2-pyrrolidone (NMP) and Chloroform
solvents have been measured at T = (298.15, 303.15, 308.15, and 313.15) K. The range of (0.05-0.3)
for PEI mass fraction in NMP and (0.05-0.28) in Chloroform have been selected. Apparent specific
volume of the polymer and solvent has been computed from experimental data. Influence of
temperature and polymer mass fraction on density of polyetherimide solution have been investigated.
Results show density of both solutions will decrease by increasing temperature linearly.Also Density
followed a linear behavior with solute mass fraction, but for NMP, density will increase by increasing
solute mass fraction and for Chloroform it will decrease
