    • During the preparation of this Letter, Advincula and co-workers reported that poly(methyl methacrylate) chains can be grown from an anionic ATRP macroinitiator based on a weak polyacid [poly(acrylic acid)] adsorbed onto 400 nm polystyrene particles as a final layer of a layer-by-layer cationic/anionic polyelectrolyte coating. (See Fulghum, T. M.; Patton, D. L.; Advincula, R. C. Langmuir 2006, 22, 8397-8402.) However, the new macroinitiators described in the present work are strong, rather than weak, polyelectrolytes. Hence, they should remain highly anionic (and therefore strongly adsorbed onto the Ludox CL sol) regardless of the solution pH.
