| titleOfInvention | Process for producing polyphenylene oxide |
| abstract | A nucleus-substituted phenol (1 mol) having 1 to 4 halogen, -CN, hydrocarbon or (substituted) hydrocarbonoxy substituents is mixed in a reactor with a catalyst system comprising (a) 0.0001 mol or more of a manganese compound (halide, oxide, hydroxide or salt), (b) 10-10,000 mols of a basic compound (a hydroxide, alkoxide or phenoxide of a metal), (c) 0.001-0.3 moles of an alkanolamine R¹ -NH-R²-OH wherein R¹=H, C1-12 alkyl or hydroxyalkyl and R² is C2-12 alkylene and (d) 0.001-0.2 mol of an amine R³R⁴NH where R³+R⁴ are H, C1-24 alkyl or C7-24 aralkyl or may complete a ring, or a polyamine thereof; and the mixture is contacted with an oxygen-containing gas which reacts with the phenol, usually at 0-100°C for 0.5-20 hours. n The polyphenylene oxide produced, in solution or as a slurry, is separated, dried and extracted into pellets, which can be mixed with another polymer and molded to give a product of good impact strength. |
