    • n = 2.4. SEC's were acquired against linear polystyrene standards with a UV detector and as such do not take into account hydrodynamic differences between the linear and graft copolymers. A typical polymerization procedure is given as Supporting Information.

    • It should also be noted that the monomodal distribution for the low DP copolymers and the multimodal distribution for high DP copolymers did not depend on the level of substitution in the parent BrMePMPS. These distributions were also observed for copolymers with about 40% and 20% bromomethylation, indicating that the extended reaction times were not due to crowding of initiator sites leading to inefficient initiation, A fuller discussion of initiator efficiency and the relative activity of the grafting sites and chains will be published in a full paper at a later date.

    • The presence of low molecular weight initiating species could possibly account for this result, but the precursor polymers were reprecipitated three times and a monomodal distribution for the lower molecular weight copolymers would seem to refute this argument.
