Effect of water on the relaxational transitions in poly-amino-bis-maleimides

The different character of the effect of sorbed water on the relaxational α, β- and γ-transitions has been established by dielectric and IR spectroscopy in polyamino-bis-maleimides differing in the chemical structure of the main unit and the quantitative relations between the bound and free water calculated in respect of some of them. The character of the participation of the hydrogen bonds in the processes of molecular motion detected has been identified and a correlation between the sorption capacity of poly-amino-bis-maleimides and their structural features has been found.
