T. Alfrey et Cc. Price, RELATIVE REACTIVITIES IN VINYL COPOLYMERIZATION, Journal of polymer science. Part A, Polymer chemistry, 34(2), 1996, pp. 157-162
From data in tire literature on relative rates of copolymerization it
has been possible to evaluate two constants, Q and e, characteristic o
f an individual monomer, which appear to account satisfactorily for it
s behavior in copolymerization, The constant Q describes the ''general
monomer reactivity'' and is apparently related to possibilities for s
tabilization in a radical adduct. The constant e labs account of polar
factors influencing copolymerization.
