Abstract
The chemical interaction of chlorosulphonated polyethylene (CSM) and acrylonitrile-butadiene rubber (NBR) as network precursors in the corresponding carbon black reinforced rubber blend (50/50 w/w) was studied by using thermogravimetry (TG), Fourier-transform-infrared spectroscopy (FT-IR) and differential scanning calorimetry (DSC). It is confirmed that CSM reacts chemically with NBR at high temperatures. FT-IR studies demonstrated that in blends an isothermally induced self cross-linking takes place. The thermal stability of the obtained elastomeric materials was analyzed. It was found that the relative mass loss of rubber blends at any temperature was lower than the one of the elastomers based on pure rubbers. Class transition determinations indicated the thermodynamic immiscibility of network precursors in CSM/NBR rubber blend.
