Abstract
Phase separation points of semidilute solutions of polystyrene in deuterated cyclohexane were measured and compared with those of polystyrene in protonated cyclohexane. Theoretical calculation of the coexistence curve by using the interaction parameters extracted from small-angle scattering of neutron and X-rays has revealed that the deuteration effect on the coexistence curve is due solely to a shift of θ point, the temperature at which the binary cluster integral vanishes, while leaving other factors unaltered. The origin of this feature is briefly discussed.
