Abstract
Solubility and diffusivity have been determined for bis-(2-chloroethyl)sulfide in isotactic polypropylene at temperatures from 15 to 40C and relative pressures from 0.34 to 1.00. While the solubility in films annealed above 90C followed the normal variation with the amorphous content, the quenched film had a significantly lower amorphous volume fraction than determined from its density, 46 instead of 60%. The diffusion behavior in the film was found to be invariably Fickian and not dependent on the amorphous volume fraction of the polymer between 0.34 and 0.46. The solubility was found to be independent of the temperature over the range 15-40C, but dependent on the diffusant concentration. TRUNCATED
