Rheological Properties of Compositions Based on Modified Polyvinyl Alcohol

Developed of a method for producing structured waterproof films based on polyvinyl alcohol (PVA) and montmorillonite-polyvinylpyrrolidone mixture (MPM) to research the impact of borax, pH-environment and MPM content on the rheological properties PVA solutions and water absorption capacity of films based on them. The MPM mixture significantly affects on viscosity the characteristics of the solution polyvinyl alcohol provided their mixing in the ultrasonic field have been established.

Sorption Properties of Metal-containing Polymer-Silicate Fillers

Sorption properties of metal-containing polymersilicate fillers on regarding to different acid-base indicators have been investigated. The effect of the nature of metal and polymer modifier on the amount of active centers and specific active surface area of such material was determined. Moisture absorption of modified and not modified silicate materials has been found.
