“…One corresponds to the broadening of the transition region and the other refers to the decrease in height of tan ı at higher transition temperatures. The height and width of tan ı could be attributed to the homogeneity and crosslink density of the polymer films [36]. As the network becomes more homogeneous, tan ı peak becomes sharper.…”

“…In thermosetting latexes, a higher proportion of hydrophilic monomers are required to obtain a sufficient crosslink density. Due to the combination of acrylate backbone and crosslink density, the resulting coatings offer excellent thermal, UV, and chemical resistance …”

“…Later those hydroxyl functional latexes can be crosslinked to improve coating performance. A number of crosslinkers can be used including: isocyanate, melamine‐formaldehyde resins or cycloaliphatic epoxides . Unlike carboxylic functionalized monomers, HEMA does not dissociate under emulsion polymerization conditions, therefore its behavior is not pH dependent as is the case with acrylic (AA) or methacrylic acid (MAA) .…”

The influence of butyl acrylate (BA) and methyl methacrylate (MMA) on hydroxyl functionalized latexes was investigated. The hydrophobicity of the monomer feed was varied via the BA/MMA ratio. In addition to monitoring the effect of hydrophobic monomer feed on secondary nucleation, the polymerization kinetics and final latex properties were also obtained for comparison. Five different BA to MMA molar ratios were combined with five 2‐hydroxyethyl methacrylate (HEMA) concentrations (0, 10, 20, 30 and 40 mol% in monomer composition). All latexes were synthesized through seeded semibatch emulsion polymerization process. Particle size distributions and average particle sizes of the latexes were determined by dynamic light scattering (DLS) and qualitatively compared with transmission electron microscope (TEM) images. The BA to MMA ratio significantly influences the boundary HEMA concentration at which homogeneous secondary nucleation occurs. © 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

“…However, the HEMA content was varied from 0% (no HEMA), 10, 20, 30, 40, and 60% in the system. BA/MMA/HEMA is a commonly used system for latexes used both in research and in commercial areas . The hydrophilic properties of HEMA are very important to the self‐healing coatings.…”

Self‐healing paints would have the potential benefit of protecting the underlying substrate and extending the coating's service life. As a step toward those types of coatings, this work examines layer‐by‐layer films of branched poly(ethylene imine)/poly(acrylic acid) with the inclusion of various types of latex particles with different Tg and different compositions. Due to high mobility of the polyelectrolyte chains when plasticized with water, water enabled self‐healing of these films is demonstrated, as well as steam enabled self‐healing. The films with various latex particles show different swelling ratios, surface hydrophilicity, as well as varying ability to self‐heal scratches. This self‐healing property is studied as a function of temperature. Also, the mechanical properties such as hardness and modulus of the films are measured.
