摘要：

Anionic polyurethane ionomers designed for use as dispersants in water-soluble acrylic baking enamels were synthesized, and their structures were confirmed by infrared analysis, in on aqueous media, the surface tension of the polyurethane ionomers with different ionic or mixed ionic groups was found to increase with increased concentration of ionic groups, because of the orientation of hydrophobic groups at the air-water interface. ii was also found that viscosity in water is higher for a polyurethane ionomer with L-2,5 diaminovaleric acid hydrochloride than for a polyurethane ionomer with dimethylol propionic acid. Polyurethane ionomers with dimethylol propionic acid, p-amino benzoic acid, and mixed dimethylol propionic acid/p-amino benzoic acid were better dispersants for the wetability and dispersion of titanium dioxide in the water-soluble acrylic enamels. The degree of dispersion of titanium dioxide was Found to improve with increased agitation time and anionic polyurethane ionomer concentration. in addition, polyurethanes with dimethylol propionic acid or p-amino benzoic acid or mixtures of these acids improved titanium dioxide dispersion.
