Dendritic compositional copolymers

Percec and coworkers [184] utilized a similar strategy for the conversion of perfluorinated alkylene functionalized 3,4,5-trihydroxy benzoic acid-type dendrons into methyl methacrylate functionalized dendritic macromonomers. Characterization of the resulting linear-dendritic architectural copolymers involved DSC, x-ray diffraction, and thermal optical polarized microscopy. It was concluded that the self-assembly of the pendant dendritic mesogens forced the linear backbone into a tilted, helical ribbon-type structure. The self-assembly behavior was largely controlled by the multiplicity, composition, and molecular weights of the pendant dendritic mesogens. 

In the above reaetion, P —Cl is the dormant molecule which does not give any growth of chains [38,39]. The TEMPO mediated and ATRP procedures are commonly used for eontrolling the architecture of the chains (comb, star, dendrite, etc.), composition of the backbone (i.e., random, gradient, or block copolymers), or inclusion of functionality (chain ends, site specific, etc.) [40].
