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 (CH3)2C(CN)- end-groups in the copolymers have been examined by 13C nuclear magnetic resonance. It has been concluded that both aromatic monomers are more than twice as reactive as methyl methacrylate towards the primary radical. |
