Abstract
The reactivity of monomers in an ionic copolymerization is shown to be a function of the polarity of the substituent on the ethylenic double bond. The nonalternating tendency is explained by the absence of an alternating polar effect during the propagation step. The results seem to indicate in the case of the monomers studied here the absence of any other selective effects (e.g., steric) and furthermore that the reactivity of the carbonium ions derived from these different monomers is the same. Therefore it is suggested that: The original Wall equation, dM1/dM2 = α(M1/M2) may be applied.Keywords
