Kinetics of the Thermal Destruction of Polyvinyl Alcohol in Composites with Boron Polyoxide. Part 2. Analysis of the Products of Thermal Destruction
The effect of boric acid (BA) on the thermal destruction of polyvinyl alcohol (PVA) was studied. The pyrolysis temperatures were chosen based on the thermogravimetric analysis data. The composition of the main products of pyrolysis was determined. The mechanisms of thermal destruction were proposed for PVA and its composite with BA. The observed phenomena associated with the effect of the filler on the composition of the products of PVA pyrolysis were explained.
