The Influence of the Nature and Concentration of the Emulsifier on the Degree of Dispersion and the Stability of Artificial Latex with Positively Charged Particles

Artificial Latexes of Butyl Rubber and Styrene Diene Thermoplastic Elastomer, Stabilised with a Mixture of Silicone and Cationic Surface-active Substances

“…Previously we have shown that, when Katamin AB is used in a mass concentration of 6 wt% of the polymer, it is possible to obtain artificial latexes with a small particle diameter (≈300 nm), low polydispersity, and good aggregate and sedimentation stability [3]. Furthermore, the use of QACs in a mixture with cetyl alcohol, taken in a mass ratio of 2:1, makes it possible to increase the stability of the obtained particles through the creation of an additional structural-mechanical barrier of stabilisation in the interphase adsorption layers of the polymer particles [4].…”

“…Data on the influence of the concentration and mass ratio of the SAS mixture on the average particle size, the particle size distribution (PSD), the ζ-potential, and the stability of the polymer suspensions of DST and BR obtained after the removal of the solvent from the emulsions of polymer solutions are given in Tables 3 and 4. The total concentration of SAS mixture amounted to 9 and 10 wt% of the polymer in the case of DST and BR respectively [4].…”
