| titleOfInvention | Process for preparing polyphenylenethers |
| abstract | Polyphenylenethers are prepared by oxidative polymerization of phenols in the presence of oxygen and of organic bases (amines, by using copper-based catalysts having general formula: wheren B is a naphthiridine group, with the two nitrogen atoms placed one with respect to the other in any possible relative positions, also substituted by one or more groups such as, e.g., alkyl, cycloalkyl, arylalkyl, aromatic groups, even substituted, containing from 1 to 10 carbon atoms, alkoxy, phenoxy, haloid, dialkylaminic, carboxyl, ketonic, alkoxycarbonyl groups, nitrogroups, amidic groups, etc.; X halogen, or nitro group or perchlorate group, Y bridge compound between the copper atoms, of the pyrazole or imidazole type, z = 0, or 1, wherefore: when z = 0, a and n, either like or unlike each other, are 1 or 2; b = an integer from 1 to 3, extremes included while, when z = 1, n = a = 2 b = 3. |
