| titleOfInvention | Process for preparation of poly(aryl ether) polymers by macro monocyclic catalysts |
| abstract | An improved process for the preparation of poly(aryl ether) polymers by reacting, in the absence of dipolar aprotic solvents, an alkali metal double salt of a dihydric phenol with a dihalobenzenoid compound in the presence of a macrocyclic polyether compound having one ether ring in which oxygen atoms are separated one from the other by 2 to 3 carbon atoms, the ring having fused thereto from 0 to 4 monocyclic or polycyclic aromatic or saturated hydrocarbon nuclei. The nuclei are attached by vicinal carbon atoms thereof to adjoining ring oxygens in oxygen-carbon-carbon-oxygen arrangement. n The poly(aryl ether) polymer resins produced by the process have a low degree of coloration and excellent mechanical and electrical properties which allow them to be molded into a variety of articles. |
