Nitrogen-containing monomers. III. Reactivity ratios of N-alkyl acrylamides with vinyl monomers

The reactivity ratios in the copolymerizations of N-tert-octyl acrylamide, N-n-octyl acrylamide, and N,N-di-n-butyl acrylamide with styrene and methyl methacrylate have been determined, and the Alfrey-Price Q and e values calculated. The distributed monomer N,N-di-n-butyl acrylamide was found to be more reactive than either N-n-octyl or N-tert-octyl acrylamide, which were of about the same reactivity.
