Synthesis of Rod-Like Dendronized Polymers Containing G4 and G5 Ester Dendrons via Macromonomer Approach by Living ROMP.

High generation dendronized polymers with high molecular weight were synthesized by ROMP via macromonomer approach. The polymerization was achieved in living manner and the macromolecules exhibited rod-like conformation. Correlation between the monomer structures and the conformation of the final polymers was investigated in detail. The rigid rod conformation in solution was confirmed by both light scattering and viscometric analysis and the single polymer chains were visualized by AFM.
