The MPM mixture significantly affects on viscosity the characteristics of the solution polyvinyl alcohol provided their mixing in the ultrasonic field have been established. Composition of traces of sodium tetraborate in the aqueous solution eminent by the highest rates of viscosity. Also, designed compositions considerable influence pH at the viscosity, particularly compositions obtained in weakly alkaline environment with higher values of relative viscosity than compositions obtained in neutral and acidic environments.22-23enpolyvinyl alcoholmontmorillonitepolyvinylpyrrolidone mixturemodifierviscosityexploitation characteristicsboraxheat treatmentfilmConference Abstract© Національний університет “Львівська політехніка”, 20172Rheological properties of compositions based on modified polyvinyl alcohol / Viktoria Antoniuk, Volodymyr Krasinskyi, Natalia Khamula, Iryna Yurkiv // Litteris et Artibus : proceedings, 23–25 November, 2017. — Lviv : Lviv Polytechnic Publishing House, 2017. — P. 22–23. — (6th International academic conference «Chemistry & chemical technology 2017» (CCT-2017)).
