The role of auxiliary monomers and emulsifiers on wet scrub resistance of various latex paints at different pigment volume concentrations

JOURNAL OF APPLIED POLYMER SCIENCE, Issue 5 2009
M. Khorassani
Abstract This work is an attempt to study the effect of different latex types containing various auxiliary monomers and emulsifiers on their pigmentation and their corresponding behavior on scrub resistance. The auxiliary monomers investigated were acrylic acid (AA), methacrylic acid (MAA), and itaconic acid and the emulsifiers contained sodium lauryl sulfate (SLS) and sodium dodecylbenzene sulfonate (SDBS). It was shown that a semibatch polymerization technique which led to smaller particles and sharper size distributions is preferable. The best wet scrub results were obtained by using MAA and SLS. It was also shown that the proper selection of an auxiliary monomer generally depended on the range of incorporated pigment volume concentration (PVC). At high PVCs, AA gave better performances compared with MMA. The reverse effect was shown to occur at low PVCs. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009 [source]

Synthesis of raspberry-like silica/polystyrene/silica multilayer hybrid particles via miniemulsion polymerization

JOURNAL OF POLYMER SCIENCE (IN TWO SECTIONS), Issue 6 2007

Abstract Organic,inorganic hybrid particles have many potential applications, but almost all research has been focused on hybrid particles with one kind of inorganic nanoparticle. This article presents a novel and facile preparation approach for raspberry-like silica/polystyrene/silica multilayer hybrid particles via miniemulsion polymerization. In this method, larger, surface-modified silica particles are first dispersed into monomer droplets to form a miniemulsion, and then raspberry-like silica/polystyrene/silica multilayer hybrid particles are directly obtained when miniemulsion polymerization is performed in the presence of smaller, unmodified silica particles with 4-vinylpyridine as an auxiliary monomer. Influential parameters such as the amount of 4-vinylpyridine, the surfactant concentration, and the pH value of the system have been investigated. © 2006 Wiley Periodicals, Inc.
