Alrstraet--~3C-NMR spectroscopy has been used for examination of 2-cyano-2-propyl end-groups in copolymers of styrene (STY) with methacrylonitrile (MAN) and with vinyl acetate (VAC) prepared at 10@' using as initiator 2-cyano-2-propylazoformamide enriched in its methyl groups with carbon-13. It is d
## Azobis(isobutyronitrile) and 2-cyano-2-propylazoformamide, both enriched with carbon-13, have been used to initiate copolymerizations of o<methoxystyrene (MOS) with methyl methacrylate. The copolymers have been examined by 13C-NMR so allowing study of the end-groups derived from the initiator.
