The effects of the substituent X on the homolysis rate constants ( k d ) of SG1‐propionate type alkoxyamines (SG1‐CHMeCOOX) are analyzed by a multiparametric equation with υ , the steric constant and σ I , the polar inductive/field Hammett constant of X. An influence of long‐range polar and steric effects on k d was observed, that is, decrease in k d with increasing size of the X group and increase in k d with increasing polarity of the X group.
