Notes:
The translational diffusion process of methyl red dissolved in poly(caprolactone) diol has been investigated as a function of temperature, using the laser induced holographic grating relaxation technique. The tracer diffusion coefficients of methyl red in trans and cis forms are found to follow the WLF type of temperature dependence with the WLF coefficients identical to that associated with the shear modulus of the polymer host. The cis isomer of methyl red although about 8% smaller in size diffuses about three times slower than the trans isomer. This is interpreted as due to a stronger interaction between the cis isomer and the polymer host.
