Claims
- 1. A catalyst precursor capable of being calcined to form an active catalyst, said catalyst precursor formed by
- (a) providing a mixture comprising a slurry of a magnesium-containing compound in water and a manganese-containing compound;
- (b) adding a caustic solution to said mixture to form a precipitate;
- (c) mixing said precipitate with polyphenylene oxide to form a blend;
- (d) adding a solvent selected from the group consisting of methylene chloride, dibromomethane, bromochloromethane, and mixtures thereof to said blend in an amount to wet thoroughly said blend.
- 2. The catalyst precursor of claim 1 wherein said magnesium-containing compound is provided by magnesium hydroxide.
- 3. The catalyst precursor of claim 1 wherein said magnesium-containing compound is provided by "basic" magnesium carbonate.
- 4. The catalyst precursor of claim 1 wherein said magnesium-containing compound is provided by a mixture of "basic" magnesium carbonate and magnesium hydroxide.
- 5. The catalyst precursor of claim 1 wherein said manganese-containing compound is manganese nitrate.
- 6. The catalyst precursor of claim 1 wherein said polyphenylene oxide is poly(2,6-dimethyl-1,4-phenylene oxide).
- 7. The catalyst precursor of claim 1 wherein said methylene chloride is added to said blend in an amount sufficient to form a complex between said polyphenylene oxide and said solvent.
- 8. The catalyst precursor of claim 1 wherein said catalyst precursor is a solid mixture comprising magnesium, manganese, said solvent and poly(2,6-dimethyl-1,4-phenylene oxide).
