| titleOfInvention | Process for producing polyphenylene oxide with alkanolamine and secondary amine |
| abstract | 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) R1-NH-R2-OH (I) wherein R1 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 R2 represents an alkylene group having from 2 to 12 carbon atoms, and an amine represented by formula (II) R3R4NH (II) wherein R3 and R3 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 R3 and R4 do not simultaneously represent a hydrogen atom, or R3 and R4 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. |
