study showed that the polymerization was well controlled. By cleaving PtBA off the particles, the molecular weights of the grafted and freepolymers were found to be essentially identical. Mixed PtBA/PS brushes were obtained by the nitroxide-mediatedradicalpolymerization of styrene from PtBA particles. The M(n) of the grafted PS was found to be the same as that of the free PS formed in the solution
