HP he study of the behavior of electrolytes in mixed solvents is currently arousing considerable interest because of its practical and fundamental implications (1). Among the simpler binary solvent mixtures, those where water is one component are obviously of primary importance. We have recently compared the effects of small quantities of water on the thermodynamic properties of selected 1 1 electrolytes in sulfolane, acetonitrile, propylene carbonate, and dimethylsulfoxide (DMSO). These four compounds belong to the dipolar aprotic (DPA) class of solvents that has received a great deal of attention (2) because of their wide use as media for physical separations and chemical and electrochemical reactions. We interpreted our vapor pressure, calorimetry, and NMR results in terms of preferential solvation of small cations and anions by water and obtained...

Properties. Propylene is an olefin hydrocarbon that is a gas under ambient conditions bnt is normally stored as a liquid under pressin-e. The physical properties of propylene are given in Table 1. Thermodynamic properties are widely reported in the literature. Vapor-liquid equilibria of mixtures of propylene with other hydrocarbons and hydrogen are accurately represented by correlations for hydrocarbon mixtnres, such as the Chao-Seader correlation.

Blends of iPP with random propylene-co-ethylene copolymers have been reported to be miscible and co-crystallizable [62]. In recent years several new copolymers of propylene (PP) with higher a-olefins have been synthesized due to the introduction of new metallocene catalysts. Propylene/1-hexene and propylene/1-octene copolymers have been reported to show thermodynamic properties, storage modulus, and density that decrease in a linear pattern with increasing comonomer content [63, 64]. Blending of copolymers offers the opportunity of designing innovative materials whose properties can be suitably modulated by varying both...
