Abstract: The present paper deals with the heterogeneity of the activity and physical micro-state of propagating radical in bulk polymerization of methyl methacrylate and styrene by ESRtechnique and pulsed gradient-field NMR spin echo technique. Some discussion and equations formulaing the effect of the heterogeneity are given.
