4. The DENDRIMERS (POLYMER HYPERBRANCHE)
The dendrimers and the dendrons are assimilable arborescent macromolecules has polymers but of which size, molar mass and reactivity can be rigorously controlled during the synthesis. The dendrimers is classified among three-dimensional polymers highly ramified.

5. Dendritic architecture
According to Tomalia and Fréchet, macromolecular architectures can be divided into four large families : linear, ramified, réticulés polymers and, more recently, dendritic polymers.
