“Living radical” polymerization of styrene in the presence of a nitroxide compound

Abstract
The influence of parameters such as styrene dilution and active site concentration on the polymerization of styrene in the presence of a di‐tert‐butyl nitroxide adduct (A‐T) was examined. It is confirmed that the rate of styrene polymerization is independent of A‐T concentration, with no monomer dilution effect. An increase in radical concentration generated in the medium leads to faster propagation, but the molecular weight of the polymers formed is alway controlled by the A‐T concentration.
