Deuterium Isotope Effect on the Compatibility between Polystyrene and Polybutadiene.

Abstract

We studied the effect of deuteration of polystyrene on the miscibility behavior of polystyrene-polybutadiene blend systems. We prepared a polystyrene having its aromatic hydrogens replaced by deuterium by starting from an ordinary polystyrene and treating it with deuterated benzene in the presence of an organometallic catalyst. We also prepared, as a control, a hydrogeneous polystyrene of closely similar structure by repeating the same procedure except that this time ordinary, rather than deuterated, benzene was used. These matching pairs of hydrogeneous and deuterous polystyrenes, when mixed with a polybutadiene or a styrene-butadiene random copolymer, were shown to give practically identical cloud point curves, thus indicating that the deuterium isotope effect is negligible.
