摘要：
Miscibility in the binary system of deuterated polystyrene and lightly sulfonated polystyrene has been investigated. Small-angle neutron scattering was used to evaluate the physical state of deuterated polystyrene/polystyrene-1.67% sulfonic acid blends over a wide composition range. Scattering behaviour was found to agree with the Debye-Bueche theory indicating that the blends were phase-separated at all compositions. A large positive interaction between styrene and styrenesulfonic acid monomers is believed to be responsible for the observed immiscibility.
