Abstract:

The phase transitions and the phase state of hydroxypropylcellulose-DMAc and hydroxypropylcellulose-ethanol solutions both under an applied magnetic field and in its absence have been studied via the cloud-point method, polarization microscopy, and polarization-photoelectric measurements. The magnetic field changes the structure of solutions and increases the phase transition temperature. The higher the field strength, the more pronounced this effect. As the molecular mass of the polymer grows, the ability of its macromolecules to orient in the magnetic field tends to increase. Hydroxypropylcellulose solutions fall into the family of memory systems. When the magnetic field is switched off, the orientation of macromolecules and the increased phase transition temperature are preserved for many hours.
