Effect of the penultimate unit on radical stability and reactivity in free-radical polymerization

Abstract

Ab initio molecular orbital calculations have been used to study the effect of γ substituents (X = H, F, or CN) on the addition of 1-Y,3-X-disubstituted propyl radicals (Y = F or CN) to ethylene. It is found that, although the γ substituent (i.e. penult Show more
