Alteration of the Hygroscopic Properties in Systematic (Homologous) Series of Fibre-Forming Polymers

It was shown that the hygroscopicity and characteristic energy of sorption of water vapor by fibre-forming polymers with a systematically varied molecular composition change nonlinearly with an increase in the concentration of functional groups. Equations are proposed for calculating the sorption isotherms as a function of the molecular structure (concentration of functional groups) and supermolecular structure (degree of crystallinity) of the polymer.
