The self-condensing copper-catalyzed polymerization of macromonomer of poly(tBA) with a reactive C—Br bond (H-6) affords hyperbranched or highly branched poly(tBA).447 Copolymerization of H-1 and TV-cyclohexylmaleimide induced alternating and self-condensing vinyl polymerization.448 The residual C—Cl bond was further employed for the copper-catalyzed radical homopolymerization of styrene to give star polymers with hyperbranched structures. Hyperbranched polymers of H-1 further serve as a complex multifunctionalized macroinitiator for the copper-catalyzed polymerization of a functional monomer with polar chromophores to yield possible second-order nonlinear optical materials.325... 

Highly branched, so called hyperbranched macromolecules have recently attracted interest, because of their interesting properties, which closely resemble those of dendrimers. Vinyl monomers with pendant initiating moieties, for example, 3-(l-chloroethyl)-ethenylbenzene, have been reported to give rise to hyperbranched polymers in a process termed self-condensing vinyl polymerization [253]. Hyperbranched PIBs have been synthesized by cationic copolymerization of 4-(2-methoxyisopropyl)styrene and IB [254]. Using a similar approach the preparation of arborescent block copolymers of IB and St (arb-PIB-h-PSt) has also been reported (see above) [226].
