    The article presents the results of a study on the behavior of water-insoluble ethoxylated surfactants of different nature on the phase boundary by the method of oscillating drops and by the method of Langmuir-Blodgett films. It was shown that the water-insoluble ethoxylated surfactants form supramolecular structures and stable layers at the water/air interface.В работе представлены результаты изучения поведения оксиэтилированных нерастворимых в воде ПАВ различной природы на границе раздела фаз методом осциллирующей капли и методом Ленгмюра. Показано, что оксиэтилированные нерастворимые в воде ПАВ образуют надмолекулярные структуры и формируют на границе раздела вода/воздух стабильные слои

    Polysterene suspensions with particle diameters of 0.05-0.2 microns and narrow distribution by sizes can be synthesized at polymerization of styrene in high-disperse emulsions at high temperature and low concentration of monomer in the presence of ionic surfactant. Monodisperse polymeric suspensions with a diameter of particles 0.2 microns were prepared only in the presence of water-soluble inhibitor

Monodisperse polymeric suspensions with a diameter of particles 0.2 microns were prepared only in the presence of water-soluble inhibitor.Сформулированы пути синтеза полистирольных суспензий с узким распределением частиц по размерам и диаметрами в интервале 0.05-0.2 мкм. Показано, что монодисперсные полимерные суспензии с диаметром частиц 0.2 мкм могут быть получены только в присутствии водорастворимого ингибитора
