Summary It has been shown that macromolecular compounds possessing conjugated double bonds reveal new magnetic properties. In the first place, the presence of a sufficiently developed system of conjugate double bonds produces the phenomenon of “unpairedness” in the basic state of the system, which is manifested in pure spin paramagnetism. It may be suggested that this effect occurs for all molecules possessing conjugated double bonds, but may only be observed experimentally with the experimental techniques at present available for sufficiently large molecules. In the second place, the macromolecular systems which have been studied are characterized by properties closely similar to the antiferromagnetic properties revealed by substances with incompletely compensated antiferromagnetic interaction. This effect depends essentially on a regularized structure within the organization of all the specimens. The authors believe that further investigation involving the synthesis of polymers of this class may lead to the creation of polymeric materials with magnetic properties which, not only qualitatively but also quantitatively, will approximate to the magnetic properties of the ferrites.
