Abstract: Method and apparatus for controlling metals in a liquid are described. The liquid is contacted with a hexahydrotriazine and/or a hemiaminal material, and metal is adsorbed from the liquid onto the material. The hexahydrotriazine and/or hemiaminal material may be made from a diamine and an aldehyde.

Abstract: Condensation polymers are prepared by agitating a mixture comprising glyoxal, a monomer comprising two or three primary aromatic amine groups, an organic solvent, and water at a temperature between 20° C. and 100° C. The resulting solution can be applied to a surface of a substrate, forming an initial film. Curing the initial film layer using two or more heating steps, wherein one of the heat steps is performed at a temperature of 150° C. to 250° C., produces a cured film layer. Depending on the relative amounts of glyoxal and monomer used, the film layer can contain predominantly high Tg imine-containing units or predominantly lower Tg aminal-containing units. All film layers were highly resistant to the solvent used to prepare the polymer. The Tg of the polymer can be about 190° C. to greater than 300° C.

Abstract: A poly(aryl ether sulfone) of low polydispersity containing no detectable cyclic polymer byproduct was prepared by melt polymerization without catalyst, solvent, and base. The poly(aryl ether sulfone) can be used without further purification for the manufacture of articles. A melt composition for fabricating an article comprises the poly(aryl ether sulfone) and, optionally, one or more additives.
