“…Hawker et al reported an extended study on the impact of both dendron size and distance of anchor groups along a backbone on the achievable degree of attachment. [14] They used the narrowly distributed copolymer 1 as starting material whose content of active ester anchor group containing repeat units (x) to parent ones ( y) could be easily modified (Scheme 2). These copolymers were treated with G1-G5 Fréchet-type dendrons 2, and the efficiency of amidation to polymer 3 was Scheme 1.…”

This article divides the synthetic routes leading to dendronized polymers into two main categories (attach‐to and macromonomer) and compares their respective advantages and disadvantages. It gives a comprehensive overview on the kind of structures presently available and also spans the bridge between both polymers and molecular objects, decorated with only a few dendrons, and the structurally related, but less well defined polymers with hyperbranched side chains.

“…Graft copolymers contain polymer units that are incorporated as side chains onto a backbone polymer chain. The graft moieties can comprise various architectures, such as linear or branched chains,1–9 stars,10 fullerenes,11–13 and, more recently, dendritic units 14–40. The diversity in the structure and nature of graft units, along with that of the backbone, provides access for tailoring the properties of graft copolymers and producing specialty and advanced materials.…”

Branched polystyrene macromonomers were synthesized by the slow addition of a stoichiometric amount of either 4‐(chlorodimethylsilyl)styrene or vinylbenzyl chloride as a coupling agent to living polystyryllithium. Star‐shaped macromonomers were produced by the addition of the coupling agent alone, and hyperbranched macromonomers resulted from the addition of the coupling agent along with styrene monomer. Star and hyperbranched graft copolymers were produced by the copolymerization of the macromonomers with styrene and methyl methacrylate. The copolymers were characterized by gel permeation chromatography coupled with multi‐angle laser light scattering, 1H NMR spectroscopy, and Soxhlet extraction to determine that the macromonomers were incorporated in high yields into the copolymers. © 2001 John Wiley & Sons, Inc.

“…To obtain these copolymers, styrene based N‐hydroxysuccinimide and alkene appended monomers M2 and M3 were synthesized. Monomer M2 was synthesized from the esterification of 4‐vinyl benzoic acid with N‐hydroxysuccinimide 20. Synthesis of monomer M3 was based on the chloride displacement from 4‐vinylbenzyl chloride, using 3‐buten‐1‐ol 21.…”

Polymers containing maleimide groups on their side chains have been synthesized by utilization of a novel styrenic monomer containing a masked-maleimide unit. AIBN initiated free radical polymerization and reverse addition-fragmentation chain transfer (RAFT) polymerization was utilized for synthesis of copolymers containing masked maleimide groups as side chains. The maleimide groups were unmasked via the retro Diels-Alder reaction. Orthogonally functionalizable copolymers were obtained by copolymerization of the maleimide-based monomer with other reactive monomers to yield copolymers that are reactive towards thiol- and amine-containing molecules, or two different thiol-containing molecules sequentially via the nucleophilic thiol-ene and the free-radical thiol-ene "click" reactions.
