ABSTRACT:
Methods for preparing copper(I)-diamine-phenoxide complexes within solution, such as the polymerization medium of polyphenylene oxides, are described which utilize a copper-diamine-halide complex, an alkali metal hydroxide and a monohydroxy aromatic compound to generate effective catalysts without the scrupulous exclusion of moisture and air.
