Ammonium poly

Receptors for anions vary widely, and are in many instances either the same or modified versions of the ligands that bind transition metal ions [5-20], For example, poly amine macrocycles can bind transition metal ions, while poly ammonium macrocycles bind anions. In many instances the same ligand can bind either a transition metal ion [21-24] or an anion [25-29],... [Pg.173]

The unimolecular micellar characteristics of this poly(ammonium carboxylate) 156 were demonstrated 179 by UV analysis of guest molecules, such as pinacyanol chloride, phenol blue, and naphthalene combined with fluorescence lifetime decay experiments employing diphenylhexatriene as a molecular probe. The monodispersity, or absence of intermolecular aggregation, and molecular size were determined by electron microscopy. [Pg.89]

Superabsorbent polymers have also found limited utility as additives to soil to improve the water-holding ability. The hydogel absorbs the water and controls its release back into the soil as conditions become drier. Poly(ammonium acrylate) and poly(acrylamide) hydrogels have been studied for spray application to the soil and plants. The gels are prepared for spraying by adding water to provide a readily deformable polymer that will pass... [Pg.622]
