Polyphenylene ether containing ether end groups of formula:
wherein: R₁ is a halogen atom, an alkyl radical, phenyl, alkyloxy or haloalkyloxy; R₂ is hydrogen, a halogen atom, an alkyl radical, phenyl, alkyloxy or haloalkyloxy; X is oxygen or NR₃; and AR is phenylene or an aromatic radical constituted by 2 or 3 condensed rings.
The polyphenylene ether of formula (I) is prepared by reacting a salt of the polyphenylene ether with an aromatic nitro-derivative of formula:
含有式中醚端基的聚苯醚:
其中R₁ 是卤原子、烷基、苯基、烷氧基或卤代烷氧基;R₂ 是氢、卤原子、烷基、苯基、烷氧基或卤代烷氧基;X 是氧或 NR₃;以及 AR 是亚苯基或由 2 或 3 个缩合环构成的芳香基。
式(I)的聚苯醚是通过将聚苯醚的盐与式(I)的芳香族硝基衍生物反应制备的:
