Synthesis and characterization of amphiphilic graft copolymers with hydrophilic poly(acrylic acid) backbone and hydrophobic poly(methyl methacrylate) side chains

Polymeric Surfactants: Synthesis, Properties, and Links to Applications

“…An approach completely based on ATRP has been used to synthesize a graft PMMA-PAA copolymer 198 ( Figure 11). 389 First, methyl methoxyacrylate (MOMA) was polymerized using CuBr/ PMDETA as the catalytic system. The resulting polymer was subsequently acylated with α-bromoisobutyryl bromide to give a multifunctional initiator for the growth of PMMA-grafted chains and hydrolyzed to convert the MOMA units into AA units ( Figure 11).…”

Methods of controlled radical polymerization for the synthesis of polymer brushes

“…Of interest is the series of papers [104][105][106][107][108][109] devoted to the synthesis of brushes with a hydrophilic backbone (poly(acrylic acid) and hydrophobic side chains [poly(methyl methacrylate) [104,108], poly(n butyl methacrylate) [105], polystyrene [106,107], and poly(vinyl acetate) [109]). The scheme of synthesis of brushes with a hydrophilic backbone of poly(acrylic acid) and side chains of poly(n butyl methacrylate) applied in [104][105][106][107][108] Poly(methoxymethyl acrylate)-a precursor of poly(acrylic acid)-was synthesized for further use as a backbone.…”

PAA‐g‐PVAc Amphiphilic Graft Copolymer Synthesized by Atom Transfer Radical Polymerization

“…Atom transfer radical polymerization of MOMA was initiated by 2-MBP in bulk according to previous literatures. 7,[10][11][12] Homopolymer PMOMA (1) with narrow molecular weight distribution (M w /M n ＝1.09) was obtained via ATRP at 50 ℃. From the result of GPC (M n ＝5,800), it was calculated that every chain has about 50 MOMA repeating units.…”

“…7,[10][11][12] The structure of the hydrolyzed product was characterized by 1 H NMR and FT-IR. The disappearance of the signals of the methoxymethyl protons at δ 3.46 and 5.23 in 1 H NMR spectrum ( Figure 3B) ensured the complete hydrolysis of the PMOMA backbone.…”
