Heterogenous formalization reaction of heat treated P. V. A. film was studied.
How the distribution of formalization degree in film changed during reaction was first considered.
Sorption isotherms of congo red in P. V. F. films (15, 21, 32, 39, 43 mol%) were studied. The amount of sorbed dye is represented by Ds as described before.
The results of similar tendency as previously reported (I) were obtained.
