Abstract

original image

The influence of steric effects on the addition of alkyl radicals to alkenes important in polymerizations can be investigated by the method of competition kinetics. Cyclohexyl radicals add to α- and β-substituted acrylic acid esters at different rates—a confirmation of the model (1) obtained by calculations for the transition state of this type of reaction.
