    The goal of a new work is to prepare and evaluate the properties of water-based overspending acrylate (HAAR).
    these materials are obtained from overspending chain alcoholate resins (HAR), methyl acrylates (MMA), acrylates (BA) and acrylics (AA) through ultra-emulsion polymerization. HAR: The ratio of acrylic monosomes is as follows: 50:50 (HAAR 1), 40:60 (HAAR 2), 30:70 (HAAR 3) and 20:80 (HAAR 4)

    . Particle size increases with THER content, but collage stability, critical deformation, ζ, thermal stability and hardness are reversed.
    a better solution for sodium hydroxide
    . The collogen stability sequence of HAAR fine emulsions is HAAR 4> HAAR 3 > HAAR 2 > HAAR 1. HAAR's particle forms are mainly nucleic-shell, but acrylic and alcoholic acid particles have also been observed. In addition, as the ad angle frequency increases, all HAArs initially exhibit a decrease in η viscosity (sic). The thermal stability of HAR is lower than that of HAAR. HAAR is more resistant to 0.10 M sodium hydroxide (NaOH) solutions than HAR.
    the study was published in the Journal of Coating Technology and Research, September 2019, volume 16, issue 5, pp. 1223-1232.
