| Abstract: | Conclusions On the basis of colloid-chemical, thermodynamic, and spectral studies of the process of precipitation of PBITA and its low-molecular analogs, models have been constructed of the solvation phenomena in precipitation of PBITA.Types of complexes and their behavior in polymer (or model)—solvent—electrolyte systems in the presence of a precipitant have been examined.It has been found that the benzamide unit is responsible for the precipitation of the models and of PBITA.Values of the thermodynamic characteristics of precipitation of the models have been discussed; these additionally support an effect of precipitation mixture composition on precipitate morphology.Translated from Khimicheskie Volokna, No. 2, pp. 18–21, March–April, 1986. |
