AbstractP-V-T properties of PP/POE blends were measured by PVT dilatometer under different pressure. The specific volume (V(sp)), expansivity coefficient (alpha) of PP, POE and PP/POE blends were calculated by Tait equation, and the influence of pressure on their crystallization temperature (T(c)) were discussed. The results show that Tait equation can be used to predict the P-V-T properties of blends with partial compatibility and semi-crystallinity. The variation of V(sp) value of PP during crystallization is bigger than that of POE. With increasing the POE content, the variation of V(sp) value of PP/POE blend decreased during its crystallization. In addition, alpha of PP in molten state is bigger than that in solid state, whilst alpha of POE at solid state is bigger than that at molten state. The variation of alpha of PP/POE blend under different temperature and pressure depends on the composition of the blend. With increasing the pressure, the crystallization temperature values of PP, POE and PP/POE blends increase linearly.
