Diffusion and equilibrium studies for the system acrylonitrile-styrene-polyethylene



The solubilities of acrylonitrile and styrene in low-density polyethylene were measured at 0° and 27°C. over the entire range of compositions.

The ternary solubility data were analyzed in terms of the relationships developed by Krigbaum and Carpenter. It is shown that the behavior of the ternary system may be predicted from the Flory-Huggins interaction constants of the three pairs of binaries.

The rates of desorption of acrylonitrile and styrene from 48 mil thick sheets of polyethylene were measured at 27°C.
