Abstract

Polymerisations of 2‐vinylnaphthalene and 4‐vinylbiphenyl and copolymerisations of these monomers with methyl methacrylate have been initiated by azobis(isobutyronitrile) enriched in its methyl groups with carbon‐13. The environments of (CH~3~)~2~C(CN)‐ end‐groups in the copolymers have been examined by ^13^C nuclear magnetic resonance. It has been concluded that both aromatic monomers are more than twice as reactive as methyl methacrylate towards the primary radical.
