A series of copolymers were synthesized by chemically oxidative polymerization of p-phenylenediamine (PPD) and o-phenetidine (PHT) in acidic aqueous media. The polymerization yield, intrinsic viscosity, and solubility of the copolymers were comprehensively studied by changing the comonomer ratio, po

Poly(o-toluidine) films were electrochemically synthesized on Pt electrodes at a constant potential (0.75 V versus Ag/AgCl) from a deoxygenated aqueous solution of 0.1M toluidine dissolved in 0.1M KCl. To form permselective polymeric film electrodes, poly(o-toluidine) films at different thicknesses
A new block copolymer composed of hydrophilic polyamide as outer segments and polyoxyethylene as an inner segment was obtained by anionic polymerization of a bicyclic oxalactam, 8-oxa-6-azabicyclo[3.2.l]octan-7- one, using the isocyanate-terminated polyoxyethylene as an activator. benzyl end group w
Polymerization of o-methylaniline or o-toluidine (OT) was studied in aqueous acidic (HCl) medium with or without the use of the support of a water soluble polymer, polyacrylamide (PAAm). Poly(o-toluidine) (POT) produced with PAAm support was in the form of aqueous solution or dispersion that showed
