METHOD OF PREPARING EMULSIONS HAVING HIGH CONTENT OF INTERNAL PHASE, AND LATEXES BASED THEREON Russian patent published in 2001 - IPC

FIELD: chemical industry. SUBSTANCE: method comprises stages of (a) continuously adding liquid stream of continuous phase having flow rate R₁ to dispersant in the presence of emulsifying and stabilizing amount of surfactant of liquid stream of continuous phase and liquid stream of dispersed phase having flow rate R₂ and (b) mixing combined streams at mixing rate sufficiently constant to form emulsion having high content of internal phase R₂:R₁ corresponds to the beginning of inversion depending on R₂:R₁ ratio, and upper boundary is established slightly lower than R₂:R₁ ratio at which phase inversion of emulsion occurs. Method makes it possible to prepare monodispersed latexes with particle size of about 1 micron and which are for applying coatings where it is necessary to have controllable particle size, minimize oiling and increase stability of latex. EFFECT: more efficient preparation method. 21 cl, 4 dwg, 1 ex
