RAFT miniemulsion polymerisation of benzyl methacrylate using non-ionic surfactant

Abstract

Miniemulsion polymerisation has become widely recognised as a versatile and efficient strategy to prepare well-defined polymer latexes. In this article, we report the synthesis of poly(benzyl methacrylate) (PBzMA) latexes via...

Physical Adsorption of Graphene Oxide onto Polymer Latexes and Characterization of the Resulting Nanocomposite Particles

“…Similar observations (see Figure S7 ) were recorded for heteroflocculation between GO and nonionic PBzMA latex ( Figure 1 d, entry 5 in Table 1 ). 39 …”

“…It is noteworthy that both the latexes and GO sheets used herein were at the nanoscale. Furthermore, anionic sterically stabilized poly(potassium 3-sulfopropyl methacrylate)-poly(benzyl methacrylate) (PKSPMA–PBzMA) 38 and nonionic poly(benzyl methacrylate) 39 latexes were used to perform control heteroflocculation experiments. The polymer latexes and resulting polymer/GO nanocomposite particles were characterized via dynamic light scattering (DLS), disc centrifuge photosedimentometry (DCP), transmission electron microscopy (TEM), UV–visible spectrophotometry (UV–vis), and aqueous electrophoresis.…”

Pyridine-functional diblock copolymer nanoparticles synthesized via RAFT-mediated polymerization-induced self-assembly: effect of solution pH

“…2-Cyano-2-propyl phenethyl trithiocarbonate (PETTCCP) was prepared in-house using previously published methods. 41,42 Deionized water was obtained from an Elga Purelab Option water purification system.…”

The effect of surface-active statistical copolymers in low-energy miniemulsion and RAFT polymerization

“…[4][5][6][7] The combination of miniemulsions with controlled radical polymerizations is particularly attractive due to the higher polymerization rates and minimized termination observed when compared to traditional solution polymerizations. [8][9][10][11][12][13] Another unique property of an ideal miniemulsion polymerization is the so-called 1 : 1 copy feature whereby each monomer nanodroplet is transformed to one polymeric nanoparticle of a similar size. [14][15][16][17] Miniemulsions require high energy input to trigger their formation.…”

“…18,19 Therefore, the vast majority of reported methods necessitate high mechanical force to effectively disperse the oily monomers in water which may be problematic due to possible degradation of shear-and/or heat-sensitive monomers. 5,10,12,[20][21][22] Furthermore, high energy methods often require the use of costly and specialized equipment (e.g. high-pressure homogenizers, high-shear stirrers or sonication) which may not only be unavailable to many laboratories but also pose a high risk of metal contamination prohibiting the widespread use of miniemulsion technology.…”
