    Abstract
  • AO-80/Nitrile rubber composites were prepared and characterized. According to DMTA experiments, the peak of tan moved towards higher temperature and the peak height of tan was also enhanced while the quantity of AO-80 increased. The pvT data was obtained by pvT dilatometer under different pressures. The parameters of Tait equations were calculated. The results showed that the pvT relationship calculated by Tait equation agreed well with the qualitative observation. The value of parameter b1 decreased while the quantity of AO-80 increased. The specific volume at Tg is smaller when the content of AO-80 was higher. The value of parameter b2 increased while the quantity of AO-80 increased. The expansion of the system with temperature was higher with the increasing of AO-80. The value of parameter b3 and b4 were constants, meaning that the parameter B was constant. The specific volume of the system was mainly affected by the pressure. The average residual of pvT data between theoretical and experimental values were all less than 0.02. It is showed that the Tait equation can be used to describe the pvT relationship of this system.
