Description

Diffusion coefficient of p-nitroaniline (PNA), p-aminoazobenzene and 1, 4-diamino-anthraquinone (DAAQ) in poly (γ-methyl-D-glutamate) (PMDG) was measured by sublimation desorption method. The values of the diffusion coefficient were considerably greater than those corresponding values for polyacrylonitrile (PAN), e. g., on p-nitroaniline, at 100°C, 7.64×10-8cm2 min-1 for PMDG and 1.44×10-11cm2 min-1 for PAN.<br>Arrhenius plot of the diffusion coefficient for DAAQ changes at about 150°C. The temperature corresponds to the maximum of tan δ and is assigned to the segmental motion of main chaln of random coil portion located between α-helix and β-structure.
