Dendritic Copolymers of PLA

Dendrimers, nanoscale highly branched and reactive three dimensional tnacromolecules, become increasingly important in biomedical applications due to their specific size, intriguing structural properties such as internal voids and 

Gong et al. [172] designed and prepared a series of well-defined dumbbellshaped tri-block copolymers (Fig. 4.13(c)) consisting of comb-like PLLA and linear PEG with narrow molecular weight distributions and varied PLLA arm lengths via the sequential preparation of terminal dendronized polyhydric PEG
