The thermal stability of nylon 6,66 and ethylene-propylene-diene rubber of dynamically vulcanised blends were studied by thermogravimetric analysis. The composition of nylon copolymer and EPDM was fixed at 70/30 ratio by weight. The blends were prepared by melt mixing in a Brabender Plasticorder. Thermogravimetric analysis showed that the decomposition proceeds through a single step even though the blends are immiscible and the cross-linked blends were more thermally stable than uncross-linked blends. The kinetic parameter of the degradation process is also studied.

Abstract


The thermal stability of nylon 6,66 and ethylene-propylene-diene rubber of dynamically vulcanised blends were studied by thermogravimetric analysis. The composition of nylon copolymer and EPDM was fixed at 70/30 ratio by weight. The blends were prepared by melt mixing in a Brabender Plasticorder. Thermogravimetric analysis showed that the decomposition proceeds through a single step even though the blends are immiscible and the cross-linked blends were more thermally stable than uncross-linked blends. The kinetic parameter of the degradation process is also studied.
