Bull. 1984, 12, 55) on the influence of β- and γ-substitution on the nucleophilicity of alkyl radicals and on the selectivity of addition of alkyl radicals to olefins. Although none of their experiments is a direct analogue of a radical copolymerization, their results and conclusions are quite consistent with our own.
