Abstract
Dendritic macroinitiator compositions are provided comprising a compound of the general formula, Fx-[G-n]-I, where F is the chain end functional group of the dendrimer, x is the number of chain end functional groups, G is the dendrimer, n is the generation number of the dendrimer, and I is the initiating group. Hybrid dendritic-linear copolymers made from these macroinitators can act as highly efficient dispersing agents for a range of nanoparticles in matrix materials.
