dc.description.abstractA comprehensive model considering both diffusion and reactions simultaneously was established and the diffusion coefficient of ethylene glycol, D(e) was obtained by comparing with the desorption results in solid state poly(ethylene terephthalate). The diffusion coefficient of ethylene glycol, D(e) was found to be proportional to the volume fraction of amorphous of poly(ethylene terephthalate) sample, and it was 5.67 x 10(-8) cm2 s-1 at 230-degrees-C, chi(c) = 0.373, which is slightly higher than reported elsewhere.8 The activation energy for diffusion in solid state poly(ethylene terephthalate) was 28 kcal g-1 mol-1.-
