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 an alkoxylated tertiary amine compound having a nitrogen atom linking together three organic chains comprising hydrocarbon groups and in each of the chains at least one oxygen atom.
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.
