The effect of a weak magnetic field on melt-crystal phase transitions in the organosilicon polymer SKTV-1 in a non-uniform temperature field

The effect of weak magnetic fields (less than 0.5 T) on a dielectric is known to lead to a change in the spin state of radical pairs (triplet–singlet transitions), which, in turn, intensifies the occurrence of reactions that are spin-forbidden in the initial state. This leads to a change in the supramolecular structure of polymers, resulting in changes in their crystallization and melting temperatures. The aim of this work is to experimentally verify the change in the temperature of the melt-to-crystal phase transition after exposure to a pulsed magnetic field (PMF). Using the method of recording polarization phenomena in a non-uniform temperature field, a change in the position of temperatures characterizing the crystallization and melting processes was established using the example of the crystallizing linear organosilicon polymer SKTV-1.
