Relationship among Polymer-Polymer Interaction Energy Densities and the Deuterium Isotope Effect.
Abstract
Cloud points for the mixtures of polystyrene and poly-alpha-methylstyrene and of polybutadiene and poly-alpha-methylstyrene were measured, and the data were analyzed to determine the interaction energy densities for these two pairs of polymers. In conjunction with the value for the pair polystyrene-polybutadiene previously determined, it is shown that the relationship is obeyed fairly well. To study the deuterium isotope effect on polymer miscibility, a matching pair of deuterated and hydrogeneous polystyrenes of closely similar structure were prepared by reacting a pre-formed polystyrene with either deuterated benzene or ordinary benzene. It was found that cloud points for the mixtures of polystyrene and poly-alpha-methylstene were not affected by the deuteration of polystyrene but the mixtures of polystyrene and poly(vinyl methyl ether) showed an appreciable deuterium isotope effect. Keywords: Polymer-Polymer Interaction Energy Density, Polystyrene, Polymer Blends, Deuterium Isotope Effect, Polystyrene, Polybutadiene, Poly-alpha-methylstyrene, Poly (vinyl methyl ether).
