The amount of ..cap alpha../sub 1/ fraction, the concentration of paramagnetic centers, and the width of the line of the ESR signal have been determined for samples of mesophase pitches obtained by treating an initial petroleum pitch at 400-440/sup 0/C. The applicability of the ESR method for studying the kinetics and mechanism of the process of mesophase transformations has been shown. From the change in the parameters studied the rate constants and activation energies of the processes of the formation and growth of the aromatic regions of polyconjugation and of the accumulation of mesophase have been calculated.
