Abstract. The article presents the results of work on the development of domestic material measures of particle sizes in liquids based on monodisperse polystyrene latex beads. The method for synthesis of a series of particle size material measures in liquids by emulsion polymerization with the use of sodium stearate as the emulsifier is proposed. Material measures of particle sizes in liquids with a nominal particle size value of 0.6 microns (MRH-0.6), 0.7 microns (MRH-0.7), 0.8 microns (MRH-0.8) and 1 microns (MRH-1) with values of relative error in reproducing the size (average diameter) of particles within ±5 % are produced. The results of research within the framework of pattern approval tests are presented.
Keywords: particle, polystyrene latexes, microemulsion, suspension, GET 163-2020, standard sample, emulsion polymerization, colloidal particle.
