A large group of engineering materials of steadily
increasing importance in industrial applications is composed of natural and
synthetic organic polymers. In recent years, significant progress has been made
in many areas of polymer blend and polymer matrix composite science and
technology. The examination of the interaction of aliphatic hydrocarbons with
macromolecular systems is important for various industrial applications. The
transport behavior of EPDM/PVC composites has been studied using the three halogenated
hydrocarbons; methylene chloride, chloroform and carbon tetrachloride, which
are part of the homologous series of the chloromethanes, as probe molecules. Peroxide and sulfur were employed
to crosslink the matrix. It was investigated how the crosslink density,
penetrant type, and crosslinking system
type affected the transport property. Among the chloromethane group, there is a
peculiarity that can be observed: sorption increases with increasing molar volume or the amount of
chlorine atoms, as would be
expected from basic solubility parameter considerations. The
mechanism of transport
was found to be deviated slightly from Fickian trend. The differences in the
equilibrium uptake can be explained on the basis of morphological changes.
