    • A process for producing a plyphenylene oxide is disclosed, comprising oxidative polymerization of a nucleus-substituted phenol with an oxygen-containing gas in an organic solvent in the presence of a catalyst system comprising a manganese compound containing at least one divalent manganese salt, at least one basic compound selected from hydroxides, alkoxides or phenoxides of the group IA metals of the Periodic Table and hydroxides or oxides of the group IIA metals of the Periodic Table, an alkanolamine represented by formula (I)R.sup.1 --NH--R.sup.2 --OH (I)wherein R.sup.1 represents a hydrogen atom, an alkyl group having from 1 to 12 carbon atoms, or a hydroxyl-substituted alkyl group having from 1 to 12 carbon atoms; and R.sup.2 represents an alkylene group having from 2 to 12 carbon atoms, and an amine represented by formula (II)R.sup.3 R.sup.4 NH (II)wherein R.sup.3 and R.sup.3 each represents a hydrogen atom, an alkyl group having from 1 to 24 carbon atoms, or an aralkyl group having from 7 to 24 carbon atoms, with proviso that R.sup.3 and R.sup.4 do not simultaneously represent a hydrogen atom, or R.sup.3 and R.sup.4 may be taken together to form a ring. The polyphenylene oxide produced has improved planar impact characteristics without failure in other properties and is, therefore, suitable as a starting material for the production of polyphenylene oxide-based polymer alloy.
    • 公开了一种生产聚苯醚的方法,包括在包含含有至少一种二价锰盐的锰化合物的催化剂体系的存在下,在有机溶剂中将含有取代的苯酚与含氧气体氧化聚合,至少 选自元素周期表的IA族金属的氢氧化物,烷氧化物或苯氧基化物的碱性化合物和周期表的IIA族金属的氢氧化物或氧化物,由式(I)表示的链烷醇胺R1-NH-R2-OH(I )其中R1表示氢原子,具有1至12个碳原子的烷基或具有1至12个碳原子的羟基取代的烷基; R2表示碳原子数2〜12的亚烷基,式(Ⅱ)表示的胺R3R4NH(Ⅱ)其中R3和R3各自表示氢原子,碳原子数为1〜24的烷基或 具有7至24个碳原子的芳烷基,条件是R 3和R 4不同时表示氢原子,或者R 3和R 4可以一起形成环。 所生产的聚苯醚具有改善的平面冲击特性,而其它性能没有破坏,因此适合作为聚苯醚类聚合物合金的制造原料。
