AB The influence of montmorillonite (MMT) on the thermal properties of polyvinylpyrrolidone (PVP) was studied by differential thermal and thermogravimetric analyses. It was found that the samples of the montmorillonite-polyvinylpyrrolidone mixture are characterized by higher thermal stability than the sample of pure PVP. It is shown that the degree of increase in the temperature of the beginning of destruction depends on the ratio of the mixture's components. It was found that the composition MMT:PVP = 1:7 has the highest heat resistance (260 °C), while pure PVP begins to degrade at a temperature of 200 °C.
