Polyfunctional chelating agents

The metal chelate polymers contain metal ions joined to one another by polyfunctional chelating agents. Examples are the linear polymers prepared from Schiff bases by mixing a solution of the base with a soluble metal salt. The insoluble polymer is precipitated (Marvel and Tarkoy, 1958) ... [Pg.557]

Polyfunctional Chelating Agents for Improved Durability of Epoxy Adhesion to Steel... [Pg.119]

Chem. Descrip. Mixt. of polyfunctional org. and inorg. substances Uses Peroxide bleach bath stabilizer, dispersant, chelating agent for bleaching cel-lulosic fibers and their blends in pad-steam, long liquor, or cold-pad batch applies. dispersant promoting suspension and flushing of silicates for reduction/prevention of silicate deposits on fiber and equip. [Pg.882]

Polyfunctional mercaptoester chelators have been synthesized and evaluated as potential coupling agents for the adhesion of epoxy resins to steel. The adhesive systems were evaluated by subjecting torsional joints to shear failure after accelerated immersion testing in distilled water. [Pg.133]

DeNicola and Bell have reported attempts to improve durability of epoxy-bonded steel joints using coupling agents containing )8-diketone and polyfunctional mercaptoester chelating groups. The success of this approach again depends on the hydrolytic stability of the chemical bonds formed with the oxide surface. [Pg.379]
