Synthesis of spiropyran-containing random copolymer by atom transfer radical polymerization and its complexation with metal ions

Abstract: (2015) Synthesis of spiropyran-containing random copolymer by atom transfer radical polymerization and its complexation with metal ions, Designed Monomers and Polymers, 18:6, 574-582, DOI: 10.1080/15685551.2015 An amphiphilic random copolymer containing a monomer 2-(dimethylamino) ethyl methacrylate (DMAEMA) and a light-responsive unit 1′-(2-acryloxyethyl)-3′,3′-dimethyl-6-nitrospiro-(2H-1-benzopyran-2,2′-indoline) (SPMA) was synthesized by atom transfer radical polymerization. The solvatochromic and light r… Show more

“…Under acidic conditions, i.e., pH < 3.94, O/W emulsion could be stabilized as a result of the protonation of DMAEMA unit, making the emulsifier surface more hydrophilic. When pH was adjusted to more neutral or basic conditions, i.e., pH > 5.80, deprotonation of DMAEMA unit could promote the formation of more lipophilic surface, so the phase inversion from O/W to W/O was observed. Nevertheless, as pH elevated over 9.86, the stability of emulsions significantly decreased and even demulsification occurred due to the disintegration of micelles.…”

“…In our previous work, [26] we have synthesized the copolymer whose feed molar ratio is 1:20 (SPMA:DMAEMA) and the actual molar ratio is 1:30.4. A series of copolymers with different feed molar ratios are prepared using the same procedure in this work.…”

“…However, this approach has not been widely investigated because natural macromolecules have simple functional groups [25,26]. SPA (an acrylate of SP-OH) and methacrylate of SP-OH are common monomers having a vinyl group; thus, their copolymerization with other monomers [29][30][31][32][33][39][40][41][42][43] has been conducted to prepare and investigate many copolymers with interesting properties.…”
