Synthesis of poly(butyl acrylate)‐poly(methyl methacrylate) core–shell nanomaterials of anti‐crease‐whitening properties

Abstract

Core-shell nanomaterials of poly(butyl acrylate)-poly(methyl methacrylate) were synthesized using a differential microemulsion polymerization method for being used as polyacrylate-based optical materials, which meet the requirement of anti-creasewhitening and proper mechanical strength. The effects of reaction temperature and surfactant amount on the particle sizes, as well as the effect of reaction temperature on the conversion and solid content were investigated to reveal the dependence of the application properties on the reaction conditions. The spherical morphology of core-shell nanoparticles was also studied via transmission electron microscopy. The resulting polymers with a core-shell monomer ratio of butyl acrylate/methyl methacrylate at 32/10 (vol/vol) demonstrated the optimal balanced properties in the anti-crease-whitening and mechanical property, confirmed by the visible light transmittance measurement and the dynamic analysis of the viscoelastic properties of the synthesized core-shell nanomaterials. The smaller the particle size, the better the transparency of the resulting polymer films. V C 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 39991.

Aqueous poly(vinyl acetate)-based core/shell emulsion: synthesis, morphology, properties and application

“…7 The investigations on CS latex featuring well-dened morphology have largely become an increasingly important interdisciplinary research eld, not only because of the tremendous demand of modern material science, but also of their scientic importance in the areas of colloid and interface. [8][9][10][11] Since the rst CS emulsion product was marketed as K-120 by Rohm & Haas in 1957, CS emulsion has been continuously developed and widely used in a variety of everyday products, such as advanced materials, [12][13][14][15] architectural coatings and adhesives, [16][17][18][19] drug carrier, 20,21 electronic industry [22][23][24] and membrane separation. 25 It gradually becomes the leading edge of emulsion polymerisation from both industrial and academic perspectives.…”

Cationic microgel emulsion with a high solid content by a multistep addition method in inverse microemulsion polymerization

“…For decades, most studies that have aimed to increase the ratio of monomer to surfactant have focused on oil‐soluble monomers, such as styrene and methyl methacrylate. The processes have included mainly multistep addition, precursor emulsions polymerization, semicontinuous feeding, differential feeding, Winsor I‐like methods, and the two‐stage addition of the surfactant . However, these methods are rarely applicable in the inverse microemulsion polymerization of acrylamide (AM) solution because of the distinctly different properties of the monomer, dispersed phase, and surfactant.…”
