trapped by carbon black surface and the polymerization is retarded. During the polymerization, a part of growing polySt radicals was trapped by carbon black surface; the percentage of grafting was very small. This indicates that very low molecular weight of polySt was grafted onto the surface in toluene.

On the contrary, in ionic liquid growing polySt radicals with relatively high molecular weight were trapped by carbon black surface to give polySt-grafted carbon black, because of stabilization of radicals in ionic liquid (Scheme 2.8).
