“…A highly branched poly(acrylic acid) film attached to a flat gold surface has been successfully applied to a number of technical applications including corrosion inhibition, chemical sensing, cellular engineering, and micrometer-scale patterning, due to an extremely high density of functional groups at the surface [107]. The surface chemistry and interfacial properties of hyperbranched polymers have also become fields of growing interest [2,[108][109][110][111][112][113][114][115]. Figure 14 summarizes hyperbranched, branched, and linear polymers grafted on surfaces.…”

This review summarizes recent advances in the synthesis and characterization of hyperbranched (meth)acrylates. We will focus on self-condensing vinyl (co)polymerization as an effective method for the synthesis of hyperbranched polymers. Molecular parameters of hyperbranched polymers obtained by self-condensing vinyl (co)polymerization are discussed from a theoretical point of view. Solution properties and melt properties of the resulting hyperbranched poly(meth)acrylates and poly(acrylic acid)s are reviewed. A novel synthetic concept for preparing hyperbranched polymer brushes on planar surfaces and nanoparticles is also described.

“…In short, synthesis of PAA on gold surfaces occurs through hydrolysis of the ester groups of poly-(tert-butyl acrylate) that is covalently attached to a MUA monolayer (Fig. After washing with 0.1 M HCl in EtOH followed by pure EtOH and drying with N 2 , the polymer films were activated again with chloroformate and reacted with DMEDA for another hour [5]. To make PAA=DMEDA-modified gold (Fig.…”

“…Surface-grafted poly(acrylic acid) (PAA) films are attractive for modifying electrodes because their -COOH groups can be easily derivatized to prepare a variety of functionalized surfaces [1][2][3][4][5]. This control over film functionality should make PAA films especially versatile for applications in chemical sensing [3,4].…”

“…This opens a wide range of application fields, e.g. surface and viscosity index modifiers [1][2][3][4] and compatibilizers. [5][6][7] Numerous synthetic methods have been investigated for preparing graft polymers in the last years including radical graft polymerizations which can be performed by the use of chain transfer reactions, [8] radiation-induced polymerization, [9] light polymerizations, [10] and mechanics.…”

Summary: Grafting of terminal epoxide‐functionalized polystyrene onto poly[styrene‐co‐(2‐hydroxyethyl methacrylate)] or poly[(butyl acrylate)‐co‐(2‐hydroxyethyl methacrylate)] backbones was carried out by coupling reactions catalyzed by boron trifluoride. The functionalized backbones were prepared by free radical copolymerization of 2‐hydroxyethyl methacrylate (HEMA) with styrene or butyl acrylate. For the synthesis of terminal functionalized polymer chains a side reaction of the TEMPO‐mediated free radical polymerization of methacrylates could be used successfully to convert TEMPO‐terminated polymers into terminal epoxide‐functionalized polymers by the use of glycidyl methacrylate. The number of epoxide units attached to the backbone was directly related to the TEMPO concentration during the disproportionation reaction. Taking P(S‐co‐HEMA) as well as P(BuA‐co‐HEMA) backbones in coupling reactions with different epoxy‐functionalized polystyrenes in the presence of boron trifluoride, graft polymers with up to 7 and 37 side chains per backbone were produced.Molecular weight distribution curves of a linking experiment between P(BuA‐co‐HEMA) backbones and epoxide‐functionalized polystyrene side chains.magnified imageMolecular weight distribution curves of a linking experiment between P(BuA‐co‐HEMA) backbones and epoxide‐functionalized polystyrene side chains.
