Abstract
|
In this work, a batch chamber was designed to measure the solubility of (n-hexane) in the
acrylonitrile-butadiene-styrene (ABS) and poly styrene-co-acrylonitrile (SAN) at diffirent
temperatures and pressures. The designed high pressure chamber consisted of the self-sealing cell
equipped to the pressure controller. The polymer samples were saturated by n-hexane in high
pressure and the solubility and diffusivity of n-hexane in samples were measured by the same
apparatus. The effect of different foaming conditions on the solubility of n-hexane in the samples
was examined. The results show that the solubility and diffusivity was increased by saturation
pressure increment. As well, the diffusivity of n-hexane was increased by increasing of the
temperature.
