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:where
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.
聚苯醚是在氧气和有机碱(胺)的存在下,使用铜基催化剂通过氧化聚合法制备的,其通式如下: 式中
B 是萘甲脒基团,两个氮原子在任何可能的相对位置上一一对应,也被一个或 多个基团取代,例如烷基、环烷基、芳烷基、芳香基团(即使是取代的),含 1 至 10 个碳原子、烷氧基、苯氧基、卤素、二烷基氨基、羧基、酮基、烷氧基羰基、硝基、酰胺基等;
X 卤素、或硝基、或高氯酸盐基团、
Y 铜原子间的桥式化合物,属于吡唑或咪唑类、
z = 0 或 1,因此:当 z = 0 时、
a和n,无论是否相同,均为1或2;
当 z = 1 时,b = 1 至 3 的整数,包括极值、
n = a = 2
b = 3.
