| Sumario: |
The kinetics of thermal degradation process on thermoplastic polyurethanes (TPUs) adhesives with hydrophilic
nanosilicas was studied using isothermal thermogravimetric analysis within the temperature range from 360 °C to 460 °C
in nitrogen. The effect of nanosilicas with different hydrophilic degree in the thermoplastic polyurethanes was
investigated. It was found that the thermoxidative degradation of polyurethane-silica nanocomposites takes place in one
step. An analysis of the isothermal methods to evaluate kinetic parameters of decomposition of solids from isothermal
thermogravimetric data is presented. Patents WO07146353A2 and US20070292623A1 have some relevant information
about the topic develop in this study, because the principle in both cases relies on the interactions between reactive groups
in the polymer (TPUs) and the silanol in the silica nano-particles. |
