Electron spin resonance spectroscopy has been used, in conjunction with the spin-trapping technique (employing 2-methyl-2-nitrosopropane), to identify (and distinguish between) polystyrene and poly(vinyl acetate) propagating radicals. The technique has also been used to establish the relative concen
## Abstract The bulk copolymerizations of acrylonitrile (AN) with vinyl acetate (VAc) initiated by azobisisobutyronitrile (AIBN) and the suspension copolymerization of AN with VAc and sodium methallylsulfonate (SMAS) in water with a Na~2~S~2~O~5~βNa~2~ClO~3~ redox initiator system at 65Β°C, were inv
