Four samples of poly(ethy1ene terephthalate) film of various crystallinities and orientation were dyed with p-nitroaniline and disperse dyes. When these films were heated under a 2-3 X lo-\* mm Hg vacuum at a specified temperature T, the dye sublimed out of the dyed specimen. The amount (Mr/Mm) of s
