Abstract
This paper describes thermochemical properties and decomposition characteristics of polybutadiene acrylonitrile acrylic acid (PBAN). The thermal behavior of PBAN samples containing various amounts of nitrile groups was determined by simultaneous thermogravimetric analysis and differential scanning calorimetry (TG/DSC). The results indicate that nitrile content in PBAN affects thermal behavior markedly. The influence of heating rate on the DSC behavior of the PBAN was investigated, while thermal decomposition of these compounds followed the first-order law. The kinetic parameters such as activation energy and frequency factor for these compounds were obtained from the DSC data by non-isothermal methods. Also the impact of different ratio of nitrile content in PBAN on glass transition temperature (Tg) of this terpolymer was measured.
