Dendrigraft Comb-burst Polymers

Synthesis of higher generation dendrigraft polymers is achieved by repetition of the deprotection and grafting cycles. 

Gauthier and M oiler [4] described in 1991 the use of anionic polymerization and grafting techniques to prepare poly(styrenes) with a dendritic structure. Styrene is well suited to be incorporated into a synthetic scheme aimed at producing 

For a series of reactions where the molecular weight of the branches (Mb) and the number of grafting sites per backbone chain (grafting site density,/) remain constant for each generation, the molecular weight of a generation G polymer can be predicted using equation (3). 

A geometric growth in branching functionality and overall molecular weight is
