✦ Synopsis

ln order to adapt the reduction-activation reaction of hydrogen peroxide to the polymerization of 2-phenyl-l,3-butadiene, emulsion polymerization was carried out with H202/Fe 2+ as catalyst in the presence of sodium pyrophosphate. The influences of emulsifier, iron ligand, electrolyte salt and polymerization temperature on the microstructure of the resulting polymer have been studied. It is possible to achieve a 100% cis-l,4 stereoregular structure.

## Abstract The kinetics of the emulsion polymerization of butadiene at 60Β°C in Smith‐Ewart interval III were investigated using gamma radiation to produce initiating species. The aim of this work was to determine radical desorption rate coefficients through monitoring non‐steady state kinetics. Th
