Proof of validity of expanded copolymerization equations

Generalized copolymerization equations which accounted for wide deviations from conventional copolymerization behavior of numerous systems involving highly polar or sterically hindered monomers had been previously proposed. This paper offers, for the first time, rigorous proof of the expanded equations for systems where one monomer is incapable of addition to its own radical. Empolying these equations, effects as far removed as four units from the end of the growing chain can be accounted for.
