Hydrogen-Bonding Index

Solubility of resins can be predicted in a similar way as for the solubility of polychloroprene rubbers in a solvent mixture (see Section 5.5) by means of solubility diagrams (plots of the hydrogen bonding index (y) against the solubility parameter (5). Another more simple way to determine the solubility of resins is the determination of the cloud point, the aniline and the mixed aniline points. [Pg.617]

The hydrogen bond index (HBI) was developed by Gordy [22] as a method to put on a relative scale the importance of hydrogen bonding in the mixing of solvents. Gord3 s hydrogen bond index is a scale between 0 (benzene) and 39 (water). For a particular solvent, the tendency to... [Pg.373]

The selection of solvents and solvent blends for use in coatings and inks is based upon solubility/viscosity characteristics and application/performance properties. Published solubility parameters and hydrogen bonding indexes are used to construct two-dimensional solubility maps. Methodology is described, and illustrations are shown. Data are provided on evaporation times of neat solvents, viscosities and dry times of polymer solutions, electrostatic characteristics of solvents, and on selected solvent blend recommendations for several polymers. Unpublished test methods for flow testing and for substrate testing are provided. Combination of the results from these areas provides a viable method for practical solvent blend selection this approach is faster than random trial-and-error and can result in superior, formulated solvent blends. [Pg.121]

Instead of parameters such as dipole moment and a spectroscopic hydrogen bonding index to characterize polar and hydrogen bonding effects, Hansen (16-19) extended Equation 3 by assuming the total energy of vaporization could be written as... [Pg.646]
