Abstract
It is shown that the sorption of water vapor in the amorphous regions of a liquid-crystalline polymer is accompanied by its swelling and the swelling pressure is responsible for the first stage of destruction of the most defective regions in the mesomorphous phase. The long-term swelling of the polymer in water leads to partial destruction of liquid-crystalline structures. The mechanism of water sorption and the dynamics of macromolecules in the liquid-crystalline paraamide polymers are studied by the method of proton magnetic resonance.
