A new class of water-soluble polypyrroles (PPy) has been developed. This was accomplished by oxidative matrix polymerization of pyrrole (Py) monomer with Ce(IV) in the presence of poly(acrylic acid) (PAA), poly(vinyl pyrrolidone) (PVP), and copolymers (CP) of vinyl pyrrolidone(VP) with acrylic acid

✦ Synopsis
Water solubility of electro-active polymers in their doped state may provide a possibility for environmentally feasible manufacturing processes. Because previous results in this direction require expensive modifications or impractical template polymerization methods, we created a simple method of mixing components with a large molecular weight difference. The polymer which acts as an acidic dopant and provides water solubility, has to have the higher molecular weight. The formed complex resembles a block copolymer but in this case the polyaniline block is attached to the sulfonated polystyrene chain by strong physical interactions instead of chemical end-to-end linkage.

Small molecules that have two carboxylic functions can adsorb from water onto calcite. The adsorption site is a ؊Ca ؉ site. The mechanism of adsorption is a complexation of the ؊Ca ؉ site by the two carboxylates, similar to the solution complexation of Ca ؉؉ ions. The complex has a ring structure wh
