identifying ion interactions leading to higher melting points of the halide salts with respect to the [PF6]–salts. The changes in hydrogen bonding, C–H⋅⋅⋅π, and van der Waals interactions have been analyzed with respect to anion, functional groups, and the symmetry of the cation to establish interdependence with the compound’s physicochemical properties. It has been observed that the cation–anion interactions
A polyetherimide composition comprises the polymerization product of a catalyzed imidization product of a 3-substituted phthalic anhydride and a sulfone diamine having improved melt stability and reduced corrosivity, and a method of manufacture thereof.
