In the given work results of researches on influence of a temperaturno-time mode of crystallisation and magnetic field action on mechanical durability, magnetic permeability and thermal properties of com- posites on the basis of polymers polyethylene (PEHD), polivinylidene fluoride (PVDF) and magnetic addi- tive BaO(Fe2O3)6 are stated. It is shown that change of mechanical durability, magnetic permeability and thermal properties of investigated magnetic compositions depending on a temperaturno-time mode of crys- tallisation and processing in a strong constant magnetic field can be connected with change supermolecular structures of a polymeric matrix, interaction degree between phases and thickness of a frontier layer.
