The end groups of styrene-methyl methacrylate (St-MMA) copolymers polymerized radically with 2,2Ј-azobisisobutyronitrile (AIBN) as an initiator, which are difficult to characterize even by NMR, were investigated by pyrolysis-gas chromatography. On the resulting pyrograms, characteristic products tha
