摘要：
The mechanical properties, the temperature dependence of dynamic behaviour of SBR and post-thermal ageing properties of styrene-butadiene rubber (SBR) were investigated. The rubber specimens were heated at a temperature of 100 degrees C in a ventilated air oven with natural convection for 1, 3, 7, 14 and 21 days, respectively. The specimens were then tested in the tensile strength, elongation at break and their dynamic mechanical properties were determined by means of DMA at different frequencies and amplitudes. The dependence of the hardness ShA on the ageing was also investigated.
