| titleOfInvention | Process for extracting metal residue from poly(ether ketone ketones) |
| abstract | Metal residues are extracted from poly(ether ketone ketones) with aliphatic alpha-hydroxycarboxylic acids or aromatic ortho-hydroxycaxboxylic acids in a liquid phase, either neat or in an aqueous or a nonaqueous solution. Extraction of metal residues, which usually derive from the catalysts used in the preparation of poly(ether ketone ketones), improves both the color and the thermal stability of these polymers. |
