Resumen:
ns were investigated and compared to equivalent batch polymerizations. The high reactivity of nNMwith respect to the monomer makes it feasible to implement a minimum time policy with intermediate addition of CTA only. The MWDs ofthe minimum time runs were intermediate between the broader distributions of the batch reactions and the narrower distributions of thestarved experiments. The conversion pro®les of minimum time experiments almost coincided with those of equivalent batch polymerizations.For controlling MWDs through semibatch operations, it seems preferable to use nNM instead of other (less reactive and more common)CTAs like tert-dodecyl mercaptan or CCl4.
