Abstract

Carboxyl-containing latexes based on n-butyl acrylate differing in the type of latex stabilizing systems: containing anionic surfactants
(Dowfax 2A1, alkylsulfonate), a SNG-MA dispersant monomer, or an industrial surfomer (Emulsogen APS-100) were synthesized.
A comprehensive study of the synthesized latexes and rubbers isolated from them was carried out. The morphological study of latexes was
carried out in the initial state («live» drop) and at an increased concentration of latex particles. An analytical complex was used, including
a Leica DM-2500 research optical microscope, a Leica DFC-420 high-resolution color digital camera, and a specialized computer station.
The molecular weight characteristics of the polymers isolated from the latexes were studied using a Waters gel chromatograph. A significant
influence of the chemical nature of stabilizing systems on the size of polymer-monomer particles, surface tension, sedimentation and
mechanical stability of latexes, structure formation of latex particles, and molecular characteristics of rubbers has been established.
